The Earth's rotation. The relation between the Earth (or a person on the Earth) and the position of the stars makes it appear that the stars are in a different position as the night progresses.
This question is FAR, FAR too general. Stars in the sky? Stars in a constellation? Stars in movies? Stars in TV shows? Stars on the radio? More specificity is needed.
Stars are always present in the sky, but they may not be as visible in September due to factors like light pollution, cloudy weather, or the position of the Earth in its orbit. Additionally, certain stars and constellations may not be visible in the sky during certain times of the year.
Because when you look at in in the sky it shows so many stars it looks milky.
They appear to move across the sky because of the position of the viewer on a rotating planet with a moving field of view.
Yes, the position of Orion in the night sky does move within an hour due to Earth's rotation. As the Earth spins on its axis, the stars appear to move across the sky, causing their positions to shift gradually over time.
Stars all appear to revolve around the sky each day as the Earth revolves, but relative to each other the stars stay 'fixed'. That is because they are so distant it takes years for any of them to move appreciably.
