The Earth revolves around the Sun at an average speed of 107,200 kilometers per hour (66,600 miles per hour).

It's important to note:

* This is the average speed. The Earth's orbit is elliptical, not perfectly circular, so the speed varies slightly throughout the year. It's faster when closer to the Sun and slower when farther away.

* This is the speed relative to the Sun. From our perspective on Earth, we don't feel this movement because we're moving along with it.
