How are dwarf planets listed in the Solar System?
Planets are listed in order of distance from the Sun. For planet moons, see Moons Of All The Planets. Planets here are in very elongated orbits that go from the Kuiper Belt out to the inner edge of the Oort Cloud. Several dwarf planets out there are believed to be perturbed by Planet 9, thought to be a mini-Neptune planet at 10X Earth mass.
What are the names of the inner planets?
They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune. Jupiter, Saturn, Uranus, and Neptune are large balls of gases with rings around them. All eight planets travel around the Sun in a different orbit.
