Explanation:

Answer 2

Stars appear motionless because their speed is extremely slow​.

Do stars move?

• Yes! the universe is constantly moving and expanding and along with it moves the stars, the planets, and every celestial body inside that galaxy.

Why do stars appear to be at rest?

• The stars are constantly moving but their velocity is extremely slow.
• Also, the distance between our naked eyes and the stars is in light-years. This extremely large distance makes it difficult for us to observe minute changes in a star's position.
• Thus, the stars although being constantly in motion appear at rest when viewed by us.
