CoachThe apparent backward motion of Mars, known as retrograde motion, occurs when Earth passes Mars in their respective orbits around the Sun. This creates an optical illusion, making it seem like Mars is moving backward in the night sky. In reality, both planets continue to orbit the Sun in the same direction.

Why does mars occasionally seem to go backwards in the sky?
Mars appears to move backward in the sky during its retrograde motion because of the difference in orbital speeds between Mars and Earth. This creates an optical illusion as Earth overtakes Mars in its orbit, making it appear as if Mars is moving backward relative to the background stars.
Why does mars appear to move west to east?
It's called retrograde motion, and it's just the result of Earth, being an inferior planet, "catching up and passing" Mars relative to their orbits. When your car passes another car on the road, the other car isn't moving backwards, but if there weren't any background objects to compare it to (fenchposts, for example) it would SEEM to have reversed.

What celestial object moves backwards among stars?
The celestial object that appears to move backwards among the stars is a planet in retrograde motion. This happens when a faster-moving planet "laps" a slower-moving outer planet from the viewpoint of Earth, causing it to look like it is moving backwards relative to the fixed stars in the sky.
Why does mars appear to travel from east to west during part of the year and from west to east during the other part of the year?
Mars, like all other planets, appears to change direction due to the relative positions of Earth and Mars as they orbit the Sun. This phenomenon is known as retrograde motion and occurs when Earth passes Mars in their respective orbits. When Earth overtakes and passes Mars, Mars appears to temporarily move backward in the sky relative to the background stars, causing the change in apparent direction.
