Twenty Minutes of Star Movement

These star trails show how much the Earth is moving over just a 20 minute period of time. 

The star in the center that everything appears to be rotating around is Polaris. It is in line with the Earth’s rotational axis to the north, and as the earth spins, the stars appear to be rotating around that star. 

The surface speed of the Earth as it is spinning is different depending on where you are located. At the equator, the speed is roughly 1040 miles per hour. In Houston, Texas, where NASA is located, the speed is around 900 miles per hour.
