1. Planets: These are the major celestial bodies that orbit the sun in elliptical paths. Our solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

2. Dwarf planets: These are smaller than planets and may share their orbital space with other objects. Examples include Pluto, Ceres, and Eris.

3. Asteroids: These are rocky bodies that orbit the sun, primarily located in the asteroid belt between Mars and Jupiter.

4. Comets: These are icy bodies that orbit the sun in highly elliptical paths. They can develop a tail of gas and dust when they get close to the sun.
