The planet that moves through the background of stars most slowly is Mercury. This is because Mercury is the closest planet to the Sun and has a shorter orbit period than the other planets, resulting in a slower apparent motion against the background of stars as seen from Earth.
The apparent change in position of an object with respect to a distant background is called parallax. It is often used in astronomy to measure distances to stars and other celestial objects.
Nearby stars appear to change their position against the distant background in an annual cycle, because of the Earth's changing position 'across' its orbit. This apparent shift is called the star's "parallax".
The apparent westward movement of a planet against the background of stars is called retrograde motion. It occurs when Earth, which moves faster in its orbit, overtakes and passes the slower-moving outer planet, causing it to appear to temporarily reverse its orbital direction relative to the background stars.
Apparent magnitude.

The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.

Stars in the night sky appear fixed, since they are much further away than planets. The planets can be identified through their apparent brightness and their movement among the background stars over time.
Solar System models, especially mechanical models are called orreries.
