• Why do stars seem to travel across the sky at night differently than the moon moves?. stars rise and set like the sun and moon? the seem to stay in the same place while the earth moves in circles, is this how it works? I appreciate any explanations about the change in star positions.
• The Answer• When we look at night sky we see stars in different locations depending
on the time of night. We also see different groups of stars depending on the time of year. The reason we see stars move during the night is because the earth spins, We see the stars rise and set, just as the sun and moon do. In addition to rising and setting, however, the sun and moon have an additional motion across the sky.
• Best answer – chosen by Asker• Because the earth is constantly rotating, so the angle between you and
the stars is changing. Same reason the Sun rises and set. • I think since is 360 in complete rotation, in 24 hours a day, the earth will
turn 360 / 20=15 degrees every hour
