Question

What causes the retrograde motion of mars?
A.) Mars passes Earth since it orbits the sun faster
B.) Mars moves backwards in its orbit for a brief time
C.) Earth moves slower when it approaches Mars in its orbit
D.) Earth passes Mars in its orbit since it orbits the sun faster

Answer 1

Answer: (B) Mars moves backwards in its orbit for a brief time.

Explanation: As the Earth moves forward in its orbit, Mars will appear to slip backward compared to its more common eastward march across the sky.

Answer 2

Mars moves backwards in its orbit for a brief time is what causes Retrograde motion.

What is Retrograde motion?

In Astronomy, Retrograde motion of a body is the movement of a body at low speed in a direction that is opposite to the direct motions of solar system or of other astronomical systems .

At every 26 months, the Earth overtake the Mars with high speed and hence it move backward.

Some Early Astronomers get confused about this since they viewed the motion and tried to explain it using the geocentric theory.

Therefore, Mars moves backwards in its orbit for a brief time is what causes Retrograde motion.
