Alternate Planets, Suns, Stars, and Solar Systems Thread

Lunares: A combination of the Moon and Mars.
Lunares.png
 
ok so I combined the moon, mars, and earth and was ready to make a political map but

no europe, asia, or northern africa

this is gonna be tricky /shrug
 
Oh damn, beat me to the punch, not that I'm complaining though, this is excellent. My only quibble is I think you have Europa's land and water flipped.

And I don't want to knock you or anything, but it looks as though Io has a lot of Ganymede parts. I could always trade off and go try to map Io and letcha handle the Mede though.
I never noticed that my Io map looks like a reverse Ganymede, but truth be told all i did was take a resized Callisto and fill the major ocean with green, but leave the rest of the minor bodies of water, since according to Wikipedia:
"[Io] has the least amount of water of any known astronomical object in the Solar System"
When it comes to Europa I think both my map and Serafim's (which I used as a basemap) are correct, since once again, according to Wikipedia:
"...the darker regions are areas where Europa's primarily water ice surface has a higher mineral content."
and as far as I can see his map is based off of this:
Europa.jpg
 
I had an idea for an alternate solar system based on our own, that gives us 4 reasonably habitable worlds:

Sol: Like normal
Vulcan: A rocky planet tidally locked to the sun, the densest planet in the solar system with a gravity of 0.6g. The front is molten and the back is hot and gravelly, kept hot due to immense tidal forces.
Mercury: A small sized gas planet, with a deep red colour. It is further away from the sun than OTL
Tyche: A rocky moon of Mercury, similar to OTL Mercury.​
Venus: A hot desert planet with a CO2 atmosphere 20 times dense much as ours, temperatures of over 200 degrees Celsius and a rotation period of 60 days. it is tectonically active. Similar to OTL but much more mild.
Eros: A moon of Venus, about half the size of our own.​
Vesta: A gas dwarf planet too small to hold hydrogen but large enough to hold helium. Has an Oxygen and Nitrogen atmosphere, which gives the planet a deep blue colour. Green clouds also swarm the planet, consisting of floating algae and plant like life. It also has a faint ring system. It is tilted at a 23 degree angle to it's rotation, so all it's moons experience seasons similar to OTL.
Diana: A rocky moon of Vesta, similar to OTL moon.
Apollo: Another rocky moon of Vesta, with gravity 60% as strong as Earth's and an atmosphere of oxygen and nitrogen 0.5 times as dense as Earth's. It is a cold planet mostly covered by ice, but the equator has an average temperature of 20 degrees, which allows water to form stably and permits the growth of life on the moon.
Earth: Another moon of Vesta, similar to OTL. It orbits far away from it's parent planet which leads scientists to believe the moon was captured by Vesta.​
Mars: A super-earth with gravity 1.5 times our own and an atmosphere 9 times as dense. It orbits further away than OTL Mars. It has a surface of ice and rock, with average temperatures of -30 degrees on the equator and -100 on the poles. Occasionally some of the atmosphere falls as snow on winter.
Phobos: A moon of Mars, similar to the real Mars in our solar system.​
Jupiter: Same as OTL.
Juno: An ocean moon with liquid water covering 95% of the surface, kept warm by tidal forces. The scattered islands on the moon form due to volcanic action, as the moon is very techtonically active. The moon even has a magnetosphere. Radiation on the surface is still rather high. The atmosphere is toxic to humans, but helps retain heat. The ocean is saturated with an anti-freeze agent which keeps the ocean liquid ad -20 degrees
Europa: Same as OTL
Ganymede: Same as OTL
Callisto: Same as OTL​
Minerva: A Jupiter trojan. It is a rocky planet with gravity about the same as OTL mars. The surface is covered with patches of ice. Has a very weak CO2 atmosphere.
Saturn: Same as OTL.
Titan: Bigger than OTL, but otherwise the same.​
Ceres: Similar to OTL Uranus, but slightly smaller and with calmer winds.
Neptune: Same as OTL
Triton: Bigger than OTL, and with a slightly thicker atmosphere. Also not in a retrograde orbit.​
Pluto: A mini-Neptune orbiting very far from the sun. Basically the Planet 9 myth made real.
Persephone: A very large moon with 60% earth gravity and a thick atmosphere of noble gases. The surface has small oceans of liquid Nitrogen and Oxygen. It is kept at temperatures of around -200 degrees due to interactions with Pluto.
Charon: Decent sized rocky moon
Thanatos: A captured dwarf planet.
Thanatos-b: A moon of a moon, it is a small body barely rounded by gravity.​

Thanatos-b: A moon of a moon, it is a small body barely rounded by gravity.​
There is also a small star orbiting far away from the Sun with another intelligent species on it hellbent on eradicating humanity (we glassed a large portion of their planet with lasers.)

Nemesis: An ultra-dim red dwarf which orbits in the Oort cloud in a way so that it comes close to the Sun once every 34 thousand years. It's interactions cause anomalous orbits among dwarf planets.
Tartarus: Has molten metal seas and a thick atmosphere 100 times as dense as our own. It's gravity is 30% stronger than Earth. Because it orbits a dwarf planet, it is tidally locked to it, but the farside is the same temperature as the nearside due to the atmosphere and molten sea transferring heat.
Gaia: The habitable planet of the system, it is home to an intelligent species, which built massive orbital shades and mirrors to modulate the heat on nearside and farside, giving the planet the same climate as Earth.
L1 Solar Shade: A massive space station that shields the nearside and keeps it habitable.
L2 Solar Mirror: Another megastructure designed to keep the farside hot​
Aion: A frozen terrestrial planet, also tidally locked to Nemesis. The centre of the side the faces the sun is rather habitable. The planet has an atmosphere twice as dense as Earths, and a gravity half as strong. Thanks to the life on the near-side, the atmosphere is of similar composition to our own.
Nyx: A purple gas giant, orbiting far enough away from Nemesis so as to not be tidally locked. It is larger than Neptune but smaller than Saturn. Has a ring system that is completely white in colour.
Moros: A small rocky moon with no atmosphere. It orbits just barely beyond Nyx's Roche limit, but is too small to volcanic. This gravitational force has nearly pulverise the moon, which have resulted in the surface being made nearly entirely out of sand.
Apate: An icy moon with a sub-surface ocean.
Hypnos: A methane moon similar to Titan
Hypnos-b: Because Nemesis technically orbits the sun, Hypnos-b is a moon of a moon of a moon. Besides that the moon is rather unremarkable.​

What should the surface of a comet look like? Pockmarked with craters or something else?
Depends on its size. A large comet would be much like an asteroid, but a small one would have many more prominent places where "geysers" blew off pieces of comet.
 
Here's the updated version,
as of 7/10/17

Our new alternate solar system,
In this new timeline, there are some changes to our solar system, some planets getting warmer, Some new planets, Some planets becoming habitable, some gaining new moons,

1, Sun
Start with the center, the center of the solar system! The Sun’s estimated lifespan has grown by 2.5x . Increasing its lifespan 5 billion more years, It’s expansion is slowed by 40%, It’s white dwarf-part will last for 5x as long, As long as 21 (14 not named) other stars, Sirius, Trappist, Proxima, Alpha, Betelgeuse, Rigel, Vega, They will last long enough for small new planets, Proxima, Trappist, Alpha will still be red dwarfs, The Other stars will usually be the size of Proxima, or jupiter, (Biggest is 6.5x jupiter size) It will all be clustered into a big fraction, 3 main galactic civilizations might develop to take over all of this “Universe” (since there’s only 21 stars), The diameter of this “Universe” is only 92 lys. Proxima is just 1.2 lys away! Rigel is so bright, it’s visible in the daylight sky! (P.S other fractions of other galaxies will be clustered too. It’s not like we’re all the galaxies)

2. Mercuria,
The First planet! Mercury is a plain rocky world in our timeline. But in this timeline it’s a bit more than interesting… Mercury has a atmosphere and magnetosphere. Allowing water to form. Colonies Of The U.S, U.K, China, Japan, Australia, Russia, canada and Germany grow on the surface. It’s rotation is 2.5x shorter. About 15.5 days. About 150 million live there.

3. Vinus
Venus is like the earth But it’s atmosphere is toxic.

4. Terra & Luna
The 3rd planet

5. Alactrus
The 1st new planet!

6. Mars,
5th in line. Mars is now known as Blue and red and white, As white stands for the ice caps, Red stands for the unusually red rocks and plants. Blue stands for The Ocean. It has a atmosphere and Magnetosphere. (This was written after Juno. But let’s just say A & M now) Many animals live in the oceans and surface. It’s moons are 25x bigger and orbit farrer. Phobos is about 1.2x size of our moon. It has a atmosphere and orbits every 24 hours. Deimos is 3/4 the size of our moon. Has a small atmosphere, deimos rotates every 25 hours and orbits every 3 days. They both have simple celled life with plants.


7, Vesta & Ceres,
A duel planet system, It became like this, because of Junos’ large mass. The 2 dwarfs came too close and became a duel. They also have a atmosphere.
Allowing water to form on their surface. Small plants and animals thrive on both of the planets. Small human colonies are on the surface. Each having between 10,000 - 25,000. They also seem to have a major moon, forming a triple system. Scientists say that. In 25,000,000 years. The moon will be kicked out into the outer system or possibly be captured by one of the gas giants.
The moon is about 1 third of our moon. Vesta & ceres are also 5x bigger.

8.Pallas & Hygiea
The 2nd duel planet,

9, Juno.
Nothing much happens to juno except the moons. It gains 3 new habitable moons. The biggest of these is 2.5x the size of our moon! And the smallest is still 1.25x! The old moons are 2x the size of them in our timeline. They also all have atmospheres like earth.

Io - Io’s volcanism is reduced by 50% and it gains a atmosphere and magnetosphere. It’s warmed by large tidal forces by jupiter. It’s actually a bit hotter than earth! Water forms on it’s surface and complex celled life develop. It has 3 main islands (90% of surface is water) called Strusera, Aland and Edune. It is also NOT tidally locked to jupiter. Taking 16 hours to rotate. Human population is low, at 55 million. Axis is 19.5. Climate is similar to The Amazon. Wet and humid.

EUROPA - Europa also has oceans, Atmosphere and a magnetosphere. Tidally heating make it a bit colder than Io, But still cool. Also it has continents instead of being a water-world. They are called Cleqeth, Loarisa, Imia and Kraupand. It also has mammals and Complex ocean life. These bacteria are a “cousin” of the bacteria of Ceres & Vesta, The most popular theory is that a large chunk of ceres (Containing simple celled bacteria, By a collision.) flew near the jupiter system. Breaking up and flying in Europa, Ganymede, Callisto, and other parts of the solar system. Io just barely caught life. If it was in the position it was in 2 hours ago. Then it would have no life since there was no bacteria to hit it. Plants are very common. Animals and humans are “unusually” friendly to each other. Also the human population on here is 350 million. It rotates every 25.5 Hours and has seasons like earth with an axis of 25.5. Climate is similar to North carolina (Slovenia for europans). Snowing every so often. About ⅔ years it snows. It has 5 countries also.

Ganymede - Ganymede is a very large object in the solar system. About ¾ the size of earth! It’s cilimate is similar to that of New york (Czech republic for europans). It’s gravity is barely lower than earth’s. (see europa for life details.) It’s colonized by humans and 8 countries emerge from this. It’s populated with animals similar to that of earth. Combined population of 500 Million. Rotation peroid is 24.02 hours. Axis is 23.5.

Callisto - Callisto has a small atmosphere and magnetosphere. It’s climate is just BARELY hot for Life. Similar to Fairbanks, (Iceland for Europe) Plants are very uncommon. And Small colonies of animals and Complex bacteria grow near the equator. Where the climate is similar to Maine. It’s wet and rainy out. It’s rotation is 24.01 hours and Axial tilt is 39.5 Degrees.

(WIP)

10, Satutane,

Mimas -

Enceladus -

Tethys -

Dione -

Rhea -

Titan -

Iapetus -

11, Oranos,
Oranos is gas giant, nothing muchchanges except the moons And that it’s axis is 52.3 instead of 83 .(Dragging the moons with it) The sizes are 1.28x bigger. (P.S all moons have a & m)

Miranda - Miranda Is one of the tiniest objects in the solar system known to have life. Large Tidal forces heat up the moon to Earth-Like temperatures. Turning it into a real waterworld. Many simple ocean creatures develop, Mostly small fish. Every hundreds of miles, you’ll find small islands around 1 - 50 Miles in length. Small towns of 10,00 - 25,000 develop too. Human population is 450K. It is Tidally locked since it’s small. Climate is similar to columbia. (Or a wet Gibraltar) Water covers 98.42% Of the surface. (See europa for life details)

Ariel - Ariel is a Somewhat small moon. It’s Rotation is 1.07 earth days. It’s Climate is sliightly cooler than Miranda since it gains less tidal heating from it. Water cover’s 92% of the surface. It is one of the few Moons in the Solar system to not Develop life from The bacteria collision from ceres, It just had the right conditions to evolve life. Small land life also develop.

Umbriel -

Titania - Titania is a moderately large moon.

Oberon -

12, Neptunica
Neptunica’s (main) moons increase in size by 1.4x, (Note: Triton is not captured by neptune) (‘nother note: All moons are A & M and are spherical shaped)

Despina - Despina is the Hottest moon in the system, It’s a tiny moon, And one of the tiniest to evolve life. It is also a waterworld, 98.94% is covered. You’ll mostly find small plants. If you had a x5 magnifying glass, You would see 13.4% of the Bacteria cells. Most human colonies avoid the expensive way of floating cities. They are located near the ice caps where small tiny grasslands exist. Human population is 74K

Galatea -

Larissa -

Protheus -

Neredid - Neredid is one of the coldest objects of the solar system. Colder for Liquid nitrogeten. So it is one of the only objects in the solar system to NOT have Life.


13, Triton
Triton is the 12th planet from the sun. It has a moderately large atmosphere to gain heat.
It is barely hot to gain life. It is 2.5x more massive and 3x bigger. Nearby tidal forces from Neptune heat up the moon to life-forming Temperatures. Plants are about 2.2x darker to observe more heat. other small forms of life are only 1 - 3 inches long. Other than that you’ll only find complex bacteria. Triton is also erriely beautiful, It has been proven those bacterias are 15% similar to earth.

14, Pluto & Charon
Pluto & Charons’ Mass are 1.5x In TTL (this-Timeline) Pluto and Charon have Liquid Nitrogeten too as pluto and Charon orbit 50 years closer. Fragile bacterian colonies thrive in the liquid nitrogen on both of the planets. Pluto & Charon also during the Cold season, (They have a axis of 14.6 degrees) Bacteria migrates into the deep soils, They still for around 13 - 28 years, Although some types remain on it.

15, Platoea.

16, Eris & Haumea.
 
Here is an alternate system which I have created. Quite similar to our own, with as much realism as possible.

The first planet, Vulcan is about the size of Earth's moon. Barren, and hot. Boring. Takes around 11 days to do a lap around the sun.
3OeQOyk.jpg

Second planet, Venus. It is closer to the sun than in OTL, a bit closer then mercury, tidally locked and about 10% larger. Atmosphere is quite thinner, but it is still no place for humans.
T3NIgZj.jpg

Mercury, 3rd planet. About the size of mars, but a little larger. Barren, boring. Same orbit as Venus.
bNWarCR.jpg

Earth, the 4th planet. 10% smaller and with completely different continents.
m91TfPB.jpg

The Moon. Orbits alot closer, slightly smaller. Barren and selenic as always.
G2idm9t.jpg

Mars. Has a thicker and more vibrant atmosphere. A bit more massive and more lively. Its 2 asteroidal moons don't exist.
3YOZ6ZH.jpg

Ceres, a little larger and orbits mars. Taking 6 days to orbit around it.
CkSY0KY.jpg

Callisto. Orbits further out, is a bit more massive than in OTL. Everything else in Jupiter system is the same.
ArugMNE.jpg

Titan. No longer orbits saturn, is on its own orbit and is a planet in its own right. No moons.
89x3VUV.jpg

Uranus looks different. Actually has stripes. White planet, nothing else changed, moons in same spots.
AHY80Zo.jpg

Neptune. Changed up a bit , and has a small ring system. Pluto and beyond is the same.

3. Vinus
Vinus is like the earth But it’s atmosphere is toxic.

4. Terra & Luna
The 3rd planet. Terra is same as earth in OTL, Except that global warming and sea level rising are slowed down 30%. It also gains a new moon. And is locked in a binary orbit with Luna. Life on here is 14% more advanced. Human life expectancy is 2.3x more.

Luna - Luna is similar to OTL Moon. it’s orbit is 12 days long. It is 2.79x more massive, and 1.93x bigger.
It’s A & M. It’s day is 1.02 days. Small ocean life and Fish thrive in the oceans of luna. The water makes 73% of the surface. It also has a lot more fresh water than earth. As freshwater makes up 16% of the water.

Edinrus - Edinrus is a Moderately moon. About 1.24x the mass of OTL Moon. Most of it is in a cold icy era as it is in a mini ice age. Most of the life is located near the equator. Small mammals and plants grow even closer. It is warming around 0.01 - 0.1 fahrenheit per year.

5. Alactrus
The 1st new planet! Alactrus is a world between Earth & Mars. It’s size is .85 of earths. It’s color is mostly green too, The similaries don’t end there too. 70% of the surface is water, and Life is 75% similar to earth. Rotation is 25 hours, It has 2 moons too! Axial tilt is 26.5 degrees also!

Viryrie - This moon is the size of Ganymede, It orbits every 16 days. It rotates every 26 hours. It’s mostly a cool temperate forest world. With large oceans and ponds. Most of this life is mammmals and Ocean creatures thanks to the large amount of water.
It also has rings like Titania. Although much visible.
Floeaid - Floeaid is a moon the size of Callisto. This moon is rich in metal. It’s also somewhat cold here. It rotates every 27 days. It’s rotation is 1.2 days. Axial tilt is 19.2 degrees. Most life is located near the equator.

6. Mars,
5th in line. Mars is now known as Blue and red and white, As white stands for the ice caps, Red stands for the unusually red rocks and plants. Blue stands for The Ocean. It has a atmosphere and Magnetosphere. (This was written after Juno. But let’s just say A & M now) Many animals live in the oceans and surface. It’s moons are 25x bigger and orbit farrer. Phobos is about 1.2x size of our moon. It has a atmosphere and orbits every 24 hours. Deimos is 3/4 the size of our moon. Has a small atmosphere, deimos rotates every 25 hours and orbits every 3 days. They both have simple celled life with plants.

7, Vesta & Ceres,
A double planet system, It became like this, because of Junos’ large mass. The 2 dwarfs came too close and became a duel. They also have a atmosphere.
Allowing water to form on their surface. Small plants and animals thrive on both of the planets. Small human colonies are on the surface. Each having between 10,000 - 25,000. They also seem to have a major moon, forming a triple system. Scientists say that. In 25,000,000 years. The moon will be kicked out into the outer system or possibly be captured by one of the gas giants. The moon is about 1 third of our moon. Vesta & ceres are also 5x bigger.

8.Pallas & Hygiea
The 2nd duel planet,

9, Asteroid belt / Vallania
Some changes are made to the asteroid belt. Small object from the size of OTL Rhea to TTL Ganymede.
The diameter is .8x the size in OTL.
Which 4 of them are big and massive enough to be considered a Dwarf planet. The largest of these, Vallania is big and massive enough to be a planet. It is 1.23x the size of TTL Ganymede. And mass of 1.48x.
Simple (and complex) celled life devlop on the biggest of these dwarfs.

10, Juno.
Nothing much happens to juno except the moons. It gains 3 new habitable moons. The biggest of these is 1.95x the size of our moon! And the smallest is still 1.24x! The old moons are 2x the size of them in our timeline. They also all have atmospheres like earth.

(WIP)

11, Satutane,

Enceladus - It is another water world. Most of this world, It’s a small world. It’s one of the waterworlds of the solar system. Enceladus is manly inhabited iby small fish and underwater plants. It is tidally locked to saturn, Axial tilt is 9.3 degrees.

Dione -

Rhea -

Titan - Titan is a large moon, larger than mercury!
It’s large gravity makes the moon comfortable to move around. It now has liquid water too. Allowing mammals and large ocean creatures to develop.
Moderately large trees also thrive on this moon.
It’s rotation is 24.02 hours. Axial tilt is 24.2 degrees.

Iapetus - Iapetus is the COLDEST moon of saturn. Since Iapetus’s orbit is more than 5x as long as titan’s. It gets barely any tidal heating at all! There is lot’s of Extremophiles here. Tidal heating only warms the moon by 4 - 7 Fahrenheit. Most simple celled life here is located underground. And the small surface colonies grow near the equator. The axial tilt is 4.6 degrees.

12, Voiaica,

13, Oranos,
Oranos is gas giant, nothing much changes except the moons And that it’s axis is 52.3 instead of 83 .(Dragging the moons with it) The sizes are 1.28x bigger. (P.S all moons have a & m)

Miranda - Miranda Is one of the tiniest objects in the solar system known to have life. Large Tidal forces heat up the moon to Earth-Like temperatures. Turning it into a real waterworld. Many simple ocean creatures develop, Mostly small fish. Every hundreds of miles, you’ll find small islands around 1 - 50 Miles in length. Small towns of 10,00 - 25,000 develop too. Human population is 950K. It is Tidally locked since it’s small. Climate is similar to columbia. (Or a wet Gibraltar) Water covers 96.48% Of the surface. (See europa for life details) Axial tilt is 5.6 degrees.

Ariel - Ariel is a Somewhat small moon. It’s Rotation is 1.07 earth days. It’s Climate is slightly cooler than Miranda since it gains less tidal heating from it. Water cover’s 92% of the surface. It is one of the few Moons in the Solar system to not Develop life from The bacteria collision from ceres, It just had the right conditions to evolve life. Small land life also develop. Axial tilt is 29.4 degrees

Umbriel - Umbriel is a moderately large moon. Most resources on this planet is Iron, Gold and Oil. It’s climate can be compared to Nebraska. Most life is located into the oceans as it recently gained a atmosphere. (around 100 million years ago) axial tilt is 13.8 degrees.

Titania - Titania is a moderately large moon. It’s mostly made of icy rocks. Since tidal forces heat up the moon, Most of the ice melts. Life has existed 2.6 billion years. It is the 2nd moon to have rings. Made from a 25 km wide asteroid flew in the roche limit and collapsed into a ring. It has mammals and complex ocean life. If humans didn't settle there, wait 250 million more years and it’ll have intelligent life there.

Oberon - Oberon is a relatively large and cold moon. Average temperature is about -10 - 25 farhen. Small pockets of life devleop in the warmer regions of the moon. Most of this moon is icy and some small greenish like plants.

13, Dunicea

14, Neptunica
Neptunica’s (main) moon's increase in size by 1.4x,. It also has a large ring system even bigger than saturn (Note: Triton is not captured by neptune) (‘nother note: All moons are A & M and are spherical shaped)

Despina - Despina is the Hottest moon in the system, It’s a tiny moon, And one of the tiniest to evolve life. It is also a waterworld, 98.94% is covered. You’ll mostly find small plants. If you had a x5 magnifying glass, You would see 13.4% of the Bacteria cells. Most human colonies avoid the expensive way of floating cities. They are located near the ice caps where small tiny grasslands exist. Human population is 74K. The largest “city”, Icenburg has only 23K. Ironically, It is owned by Iceland. (the 2nd icelandic colony in space, 1st is Icelandic northern Ganymede)

Galatea - Galatea is the Possibly most habitable in this system. Animals and small trees dominate the surface. It was discovered it has the largest supervolcano, Even almost 2x the size of mars which is 2x larger than earth's’! It also has the largest drop. Which is 6 miles deep. Thanks to the deep depth and Weak gravity, It would take you about 9 minutes to fall down!

Larissa - There’s not much to say ‘about this barren moon. Except it’s usually mined for resources. Mainly because the moon contains a lot of freshwater, Iron, and Oil.

Proteus - Proteus is a moderately small moon,
It’s pretty cold (Same as callisto). Small plants and animals live near the equator. Other than that, the only things that populate the Poles are SImple celled bacteria. Complex bacteria lives 5 - 10 degrees lower/higher. Water makes up 72% of the surface.

Neredid - Neredid is one of the coldest objects of the solar system. Colder for Liquid nitrogen. So it is one of the only objects in the solar system to NOT have Life.


15, Triton
Triton is the 14th planet from the sun. It has a moderately large atmosphere to gain heat.
It is barely hot to gain life. It is 2.5x more massive and 3x bigger. Nearby tidal forces from Neptune heat up the moon to life-forming Temperatures. Plants are about 2.2x darker to observe more heat. other small forms of life are only 1 - 3 inches long. Other than that you’ll only find complex bacteria. Triton is also eerily beautiful, It has been proven those bacterias are 15% similar to earth.

16, Pluto & Charon
Pluto & Charon's’ Mass are 1.5x In TTL (this-Timeline) Pluto and Charon have Liquid Nitrogen too as pluto and Charon orbit 50 years closer. Fragile bacterial colonies thrive in the liquid nitrogen on both of the planets. Pluto & Charon also during the Cold season, (They have a axis of 14.6 degrees) Bacteria migrates into the deep soils, They still for around 13 - 28 years, Although some types remain on it.

17, Platoea Belt
Platoea was a planet. Or at least to. It was a large asteroid that was ejected into the outer solar system where it got ripped to pieces by neptune, However it didn’t become a moon. Instead it was flown even farther. Becoming a belt.


18, Eris & Haumea.

Changes for earth
The earth would likely be changed quite a bit or a lot depending if you care. Here’s some things that might happen.

NASA and the space race - The space race would be very changed. Other countries such as UK, Canada, France, Germany, Japan, Australia, And possibly many others. Could also join the space race. Early NASA conforms life in the solar system, But are surprised to see how much life is in the solar system. So the space colonies are limited to almost barren worlds. Such as Mercury, Venus, Iapetus and others.

Other forms of life -
