The planet Neptune was predicted based on discrepancies in the orbit of Uranus, which led astronomers to deduce the presence of another planet influencing its motion. Using Newton's laws of motion and gravitation, astronomers calculated the position of Neptune, which was later confirmed through observation.
A planet's backward motion in the sky is called retrograde motion. This occurs when a planet appears to move in the opposite direction in the night sky compared to its usual eastward movement.
The motion of a planet about it axis is called the rotation of a planet.
The motion of a planet about it axis is called the rotation of a planet.
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.
yes there were observations of the planet mercury but were hard to explain by Issac newtons theory of gravity as scienctists didn't have enough information to investigate more on the subject.
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.
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.
They both spin on an axis.
Generally, rotation is the term for motion in a circular manner around a fixed line (the axis).Although the term "revolution" also refers to cyclic motion, it often refers to motion around an object or other fixed point. In astronomy, revolving is used for either circular or elliptical motion of satellites, while rotating refers to the spinning of a satellite such as a planet or moon.

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.
