Question

Is the speed of Earth revolving around the sun changing?

Answer 1

Answer: First of all, I cannot give you a precise answer, because the speed of the Earth changes all the time as the Earth moves around the Sun. This is because Kepler's second law says that on its orbit, a planet will sweep equal areas in equal amounts of time.

Answer 2

30 kilometers per second

Step-by-step explanation:

the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour.
