Why is a constellation at a different location at the same time on different nights?

Please make it as short as possible! I'm very bad with astronomyWhy is a constellation at a different location at the same time on different nights?Because we are in an orbit around the Sun. Each night at the same time we are at a different point in the orbit, so the constellations have all shifted slightly from the night before. The shift amounts to about four minutes per night. For example, if you look at the constellations tonight at 10 PM, they will be in that same position tomorrow night at 9:56 PM.Why is a constellation at a different location at the same time on different nights?Because the Earth is constantly moving around the Sun, giving us a slightly different view of the sky every night.Why is a constellation at a different location at the same time on different nights?it isnt the earth just moved so it looks like it is in a different placeWhy is a constellation at a different location at the same time on different nights?
