Question: Why don't stars move in the sky?

Hi Bellis,

A good question. Stars actually move its position in the sky but for naked eyes stars appear “fixed” to the sky. As the earth’s rotation from west to east make the star appear to move in the sky from east to west during the night. In reality, the stars are in constant motion. Everything in the universe is in motion. Due to the distances to the stars – (the nearest star being 4 light years away) – their apparent motions across the sky are very small during a human lifetime and not perceived by us.
