CoachRetrograde motion is observed in planets when they appear to move backwards in their orbits from the perspective of Earth. This phenomenon occurs due to differences in orbital speeds as Earth and the other planet move around the Sun. The most well-known example of retrograde motion is seen in Mars, but all planets can exhibit this behavior.

It is now known that the celestial objects which appear to move backwards among the stars are?
The celestial objects that appear to move backwards among the stars are planets in our solar system. This phenomenon is called retrograde motion and is an apparent backward motion that occurs when Earth passes by these planets in their orbits.
Why do celestial bodies appear to move in the sky?
Celestial bodies appear to move in the sky due to the Earth's rotation on its axis. This rotation makes the celestial bodies, like the sun and stars, appear to rise in the east and set in the west. Additionally, the Earth's orbit around the sun causes the position of celestial bodies to change throughout the year.
How are planets distinguished from stars on the celestial?
planets appear to move
Why does the appear to move?
The sky does not move and you must be complete looney.
Does the celestial sphere exist physically?
