Here is something I've been working on, the setting of a story I've been writing. Its also the first map I've ever made. Comments welcome
“Barnard’s Star is an M4-class red dwarf star and the second closest star system to the Solar System at about 5.9 lightyears away. With a mass less than 15% that of Sol and a proportionately similar radius, Barnard’s Star is a small and dim star. Barnard’s Star is orbited by two planets, an unknown number of asteroids and three known dwarf planets.
Van de Kamp’s World is the outer of the two planets, whose existence was theorized by the eponymous astronomer but not proven until 2018. It is a Super-Earth with about three and a half times Earth’s mass and roughly 1.4 times Earth’s radius. Orbiting at 0.4 AU from Barnard’s Star, VdK’s World is a frigid planet far outside the habitable zone, with a surface mostly covered in ice. It is the largest known source of volatiles in the system. The planet possesses two large moons (the approximate size of Io and Pluto) named Lubbertus and Engelina after Peter Van de Kamp’s parents, as well as half a dozen known smaller satellites.
The inner and smaller of Barnard’s Star’s two planets is known as Gatewood’s World, discovered by the Daedalus Crater Radio Telescope. Classified as a near-Earth sized world, Gatewood’s World is slightly smaller and approximately as massive as Venus. The planet has a relatively thin atmosphere (~90 millibars on the surface) and like most terrestrial planets orbiting red dwarfs is tidally locked. Despite these qualities, the fact that the planet’s 0.07 AU orbit puts it directly in Barnard’s Star’s habitable zone makes Gatewood a prospect for terraforming.
Aside from centuries worth of observation, humanity’s interaction with Barnard’s Star started when the
Gan De-class interstellar probe
Niú, one of several launched by the PRC prior to World War 3, flew within 100 AU of the system in 2093, transmitting the most detailed images of the system ever seen up to that point. In 2139 the ISV
Mushika was launched towards the system, the third ISV ever launched. Like its older sisters the
Mushika carries its passengers in cryostasis for the near-entirety of its 31 year journey. The colonists, mainly a mix of Brazilians and Indians (the ship being a joint venture between the two members of SOTO) are due to arrive in-system in 2170. Time will tell what they’ll accomplish...

“Astrographical report #039 summary: We have tentatively mapped the extent of Barnard’s Star’s Oort Cloud, Emerson Belt (Kuiper equivalent), and Edward Belt. Several metallic asteroids have been identified and designated as potential mining targets. Additionally two additional dwarf planets have been identified in the outer system. We postulate their highly eccentric orbits are the reason for the provw
Niú missing them in it’s surveys. They have temporarily been designated MUSHIKA-1 and MUSHIKA-2 until proper names can be determined. See full report for more details.”
