Retrograde motion important in astronomy because it helped to explain that the planets revolved around the Sun. Retrograde motion is the ability of some objects to rotate in a direction that is opposite what is expected.
The "apparent" reverse or backwards motion of a planet as observed from Earth. The innermost planets appear to have a retrograde motion when viewed from Earth.
When Mars is in retrograde motion, it does not affect its brightness. Mars will continue to appear at its usual brightness in the night sky regardless of its retrograde motion. Retrograde motion refers to how the planet appears to move in the sky, not its actual brightness.
This motion is called retrograde motion. It occurs when a planet's motion in its orbit appears to reverse due to differences in orbital speeds and distances from Earth.
A few celestial objects appear to have retrograde motion.
Retrograde motion happens when the Earth overtakes an outer planet in its orbit. It happens around the date of Opposition when the planet is opposite the Sun in the sky. Usually planets travel from west to east along the ecliptic, but during retrograde motion they travel backwards, from east to west,.
The apparent westward movement of a planet is known as retrograde motion. This phenomenon occurs when a superior planet passes Earth in its orbit, making it appear to move backward in the sky relative to the stars.
YES. There are several meanings to "retrograde" in astronomy. In this case, I am assuming you mean the apparent "backwards" orbital motion of a planet that is sometimes seen. This is very obvious in the case of Mars. Also, all the outer planets show this "apparent retrograde motion". It's easy to forget, but Mercury and Venus also show this behaviour, but in a slightly different way.
Retrograde motion describes something by definition. It is not and has never been a theory.
Prograde motion is a counter-clockwise motion or west to east, retrograde motion is clockwise motion or east to west.
Venus and Uranus have retrograde rotation.There are other meanings of retrograde motion, but retrograde rotation fits the question best.

In astronomy retrograde is essentially a fancy astronomical way of saying backward/ opposite rotational spin. A body is said to have retrograde motion when it rotates in a direction opposite to the body it orbits. I.E. The Sun rotates counterclockwise. Venus has retrograde motion in relation to the Sun because it rotates clockwise.In astrology retrograde refers to the apparent backward motion of a body in the sky due to the Earth overtaking it in orbit about the Sun. Retrograde planets are said to express themselves more internally in a natal chart and in transit indicate periods when the affairs they relate to may resurface to be resolved at a later period when the planet goes direct.
Neptune has a moon named Triton that exhibits retrograde motion. Retrograde motion is when a moon orbits its planet in the opposite direction of the planet's rotation.
Mars was in retrograde motion in 2020 from September 9th to November 13th, and it will be in retrograde motion again in 2022 from October 30th to December 13th.
Mercury and Venus are the two planets that retrograde motion around the sun.
