Other celestial bodies
Small celestial bodies that orbit beyond Neptune. They're made up of ice and dust particles.
Celestial bodies that orbit the Sun with spherical shape but without enough mass to clear the area around the orbit
Small rocky or metalic bodies, usuallly with irregular shape. The majority are found in the Asteroid Belt
Celestial bodies that orbit the planets.
The largest planets, with gaseous or liquid surfaces and surrounded by rings
They are far away from the Sun.
