Of those objects that orbit the Sun directly, the largest eight are the planets (including Earth), with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.
These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
These are lists of planets.A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk.
The Moon's atmosphere is extremely thin, consisting of a partial vacuum with particle densities of under 10 7 per cm −3. [115] Mars (1.38–1.67 AU) [D 6] has a radius about half of that of Earth. [116] Most of the planet is red due to iron oxide in Martian soil, [117] and the polar regions are covered in white ice caps made of water and ...
