I know I sound very dumb asking this but I am still confused at how the moon moves across the sky at night. I just don’t understand how it works, is it perception? The way the sun reflects light off the moon? I know the moon orbits around the earth every 28 days but it makes no sense to me. Many thanks.
In: Physics
It crosses the sky at close to the same speed the sun does for the same reason: the earth is spinning way faster than it’s moving. It’s orbital speed is why it rises & sets at slightly different times each day (at a different rate from the changes in sunrise/sunset times) and changes phase. I.e., as it’s orbiting around the earth, it’s position relative to earth and sun changes. That doesn’t happen fast enough to observe in one look, but you can see a minor change night by night.
