The circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour.
Multiply by cosine of your latitude to see how fast the Earth is rotating where you are.
Originally posted by Don WahnMy question is, does anyone know how fast the moon is supposed to move through the night sky? It just seems that the moon shouldnt be gone for the night at 9:30. Shouldnt it be up for longer? And why did it seem to move so fast?
Any thoughts or ideas?
