...now i know stars dont follow the moon, so either the four times i have looked out there so happened to be a star in the same position each time....
or it is a UFO, if anyone in the UK can look at the Moon and see the "star" im talking about...
Yes and no.
The apparent motion we see of the stars, planets, and the moon over the course of one night is mostly due to the earth's rotation. However, the moon
itself also revolves around the earth, so its apparent motion is actually a little slower than the background stars -- i.e., the moon appears to be
moving slowly "backward" against the background stars.
That motion is so slow that it is difficult to detect over the course of a few hours, although it does result in the Moon rising about 30 to 60
minutes later relative to the background stars each night/night. You might be able to notice that movement over the course of an entire night if you
(say , fro example) measure the distance from the Moon to a star at moonrise, then measure again to that same star near the time the Moon sets.
The visible planets also move slightly differently against the background stars due to their own orbits, with the closer ones (Venus, for example)
having a faster apparent motion than the farther ones, such as Jupiter. However, they do not move as quickly as the moon in the night sky, and their
apparent motions against the background stars may take a few days the be easily noticeable with the naked eye.
