Sol

The Sol system is the birth place of humanity and sits 4.3 light-years away from its nearest neighbouring system in Alpha Centauri. It is a single star system, with Sol being a main sequence yellow star of type G2 V. There are four terrestrial planets, two gas giants, and two ice giants. Other bodies include an asteroid belt, numerous minor planets, and a large number of icy bodies that orbit beyond Neptune.

The four terrestrial planets are

  • Mercury (0.387 AU)
  • Venus (0.723 AU)
  • Earth (1.000 AU)
  • Mars (1.524 AU)

    An asteroid belt orbits beyond Mars. It includes minor planets such as Ceres, Vesta, Juno, and Pallas.

    The two gas giants are

  • Jupiter (5.204 AU)
  • Saturn (9.583 AU)

    The two ice giants are

  • Uranus (19.218 AU)
  • Neptune (30.11 AU)

      Beyond that is the Kuiper Belt (extending beyond Neptune to around 50 AU). The Kuiper Belt is a disc, similar to the asteroid belt but much larger. It includes minor planets such as Pluto, Eris, and Haumea. Marking the edge of the Solar system is the Oort Cloud, a cloud of icy planetesimals ranging from 2, 000 AU to 200, 000 AU.   1 AU (astronomical unit equals roughly 150 million kilometres.
