The Solar System

In the opinion of the International Astronomical Union at the time of writing, the Solar system consists of eight planets and their respective moons, five dwarf planets, an asteroid belt, a sun, and numerous outlying icy objects. Many people still consider one of the dwarf planets, Pluto, to be a true planet because it was counted as such for seventy years (and was the only one discovered by an American…) but the problem with this definition is that a more recently discovered and more distant planetoid, Eris, is larger than Pluto.

Our solar system is home to the planet Earth, the only known planet in the system hosting lifeforms which consider themselves intellegent. The other planets' lifeforms are far more modest.

As the general application of the term 'solar system' is based around a sun, and as each star visible from Earth (which are only a fraction of the total stars present in the universe), is a form of sun, there are many, many, many solar systems out there besides ours. This fact has been known to blow people's minds.

Summary of the current IAU definitions to clear up all this editing bollocks
