What is Earth’s approximate rate of revolution?

At a location in the Northern Hemisphere, a camera was placed outside at night with the lens pointing at a group of stars. The shutter was left open for a few hours, resulting in the image of star trails shown below. The star at the center of the image did not leave a trail because the star is
