Final answer:
The movement of the sun and stars is influenced by the rotation of the Earth and its orbit around the sun.
Step-by-step explanation:
The movement of the sun and stars
The movement of the sun and stars is a result of the rotation of the Earth on its axis and its orbit around the sun. The sun appears to rise in the east and set in the west due to the Earth's rotation. The stars appear to move across the sky due to the Earth's rotation as well.
Additionally, the stars have their own motion relative to the observer on Earth. This is known as proper motion and is caused by their actual movement through space. However, over short periods of time, the proper motion of stars is not easily observable without precise measurements.
