The movement of the stars
At first the beginner is disconcerted by the apparent movement of the stars. The stars maintain their apparent distance from each other, but they appear each night in a somewhat different position and then move on further. Some stars and constellations are visible all year round in the night sky, but others disappear. After a few hours in the western horizon, new stars and constellations then appear in their position. “The movement” of the stars is very slow and is hardly detectable by observers.
