Worlds

Every world, by distance from the Sun

The Sun and its eight planets have full pages. The larger moons, the dwarf planets and the asteroids and comets on the atlas have outline pages: their measured orbits and sizes now, the rest still being written.

Distance from the Sun, on a scale where each step is a multiple: the near worlds would otherwise be lost in the first sliver. One au is the Earth’s distance from the Sun. Each line runs from the nearest point of a world’s path to the farthest, with the dot at its average distance. Planets are solid and have full pages; everything hollow has an outline page still being written. Sedna’s path runs on past the edge, to about 1,000 au.
Inner planets
0.3 to 1.7 au. Four rocky worlds close to the Sun, and the rocks that cross their paths.
Asteroid belt
1.7 to 4.5 au. Rubble between Mars and Jupiter.
Giant planets
4.5 to 31 au. Four giants and most of the Sun’s moons.
Kuiper belt
31 to 100 au. Icy worlds past Neptune, among them most of the dwarf planets.
Far out
100 to 700 au. Long paths that reach far beyond the planets.

Further out still, the Oort cloud has no outline page yet; you can fly out to it in 3D. Stars have their own pages under Stars.
