What is a retrograde planet?
SpacePlanet motion
Quick Answer
A retrograde planet is one that appears to move backward in the sky for a time because of relative orbital motion.
The Full Story
Planets do not usually reverse direction in space; retrograde motion is an apparent effect seen from Earth. It happens when Earth and another planet pass each other in their orbits, making the other planet seem to drift westward against the stars for a period. Mars shows this effect prominently during opposition. The term can also describe a planet or moon that truly orbits in the opposite direction of most bodies in the system.
Key Facts
1.The backward motion is usually only apparent
2.Mars is famous for retrograde loops
