The Sun
Explanation:
The sun does not move or rotate and hence cannot retrograde, however the other planets rotate. Some astronomers define retrograde motion as the Westward movement of the planets relative to the sun, based on this definition, all the planets experience retrograde movement. On the other hand, while some astronomers define retrograde motion as the movement that the other planets make when earth passes them while orbiting the sun. Based on this second classification, Mercury and Venus do not retrograde relative to the earth because they move faster than the earth.

The terrestrial planets are closer to the sun, they are smaller that the jovian planets, they have less moons, and do not have a lot of gases on the surfaces. The jovian planets are farther away from the sun, they are much bigger than the terrestrial planets, have a lot of moons, at least two planets are gas giants, and at least two have rings, and they have more gases. Temperatures can be a difference too.
A^2 + b^2 = c^2
18^2 + 9^2 =
324 + 81 = c^2
405 = c^2
take the sq root
= around 21.12
