List of planetary bodies

From Wikipedia, the free encyclopedia

This table lists the Solar System's planetary bodies, which include planets, dwarf planets and planetary-sized moons [1] [2]. It accumulates information about planetary-sized bodies in the Solar system and their properties, focusing on those specific to planetary-sized objects and important for possible future solar system colonization. Internal structure (planetological model) of the bodies, where data exists, is indicated as well. Bodies are grouped by planet-satellite system and major Solar System regions. The moons follow their primary in order of distance.

[edit] Notes

  1. ^ Bodies that are large enough that their shape is determined by gravity, as per the criterion for distinguishing between dwarf planets and small solar system bodies. They are mostly larger than 1000 km in diameter.
  2. ^ Sources:
  3. ^ Calculated as \frac{1}{|\frac{1}{\rm rotation period}-\frac{1}{\rm solar orbit period}|}.
  4. ^ Combined surface area of all objects in the system that have a solid surface and exceed 900 km in diameter.
