Stars appear to move through the night sky at a rate of 15 degrees per hour due to the Earth's rotation on its axis. The Earth completes one full rotation (360 degrees) in approximately 24 hours, leading to the observable movement of celestial objects across the sky. This rotation causes stars to rise in the east and set in the west, creating the illusion of their movement. Consequently, the apparent motion of stars is directly tied to the Earth's rotational speed.
Since the Earth is a solid and must rotate all in one piece, every point on Earth rotates from west to east at the rate of almost exactly 15 degrees per hour.
Most satellites in low Earth orbit rotate around the Earth approximately 15 times per day. This means they orbit the Earth about every 90 minutes.
At the equator, the rotation of the Earth causes a person to move at approximately 1,037 miles per hour from west to east. This speed corresponds to the Earth's rotational velocity at the equatorial region.

Light travels at about 300,000 metres per second. The time taken for that light to reach us would depend on the stars distance.
The Earth turns about 361.02 degrees per day, on a sidereal basis, measured with respect to far distant stars.
1.5 billion stars per 1000 light years.
Stars appear to move through the sky at the rate of 15 degrees per hour due to the rotation of the Earth on its axis. As the Earth rotates, it creates the illusion that the stars are moving across the sky at this constant rate. This phenomenon is known as diurnal motion.

In reality, each star has its own "proper motion", but the stars are so far away that no human lifetime is long enough to notice any motion. But the Earth DOES move, and we live on the moving Earth. Not only is the Earth moving in its orbit around the Sun, at about 66,000 miles per hour, but the Earth also is spinning, once per day. It is the rotation of the Earth, and our positions riding the Earthly merry-go-round, that make it SEEM like the Sun, Moon and stars are moving. Because the Earth spins west-to-east, the appearance is that the stars move east to west.
