Earth's Motion and Orbit Concepts

The video explains that even when standing still, we are moving as Earth orbits the Sun. Astronomers have calculated Earth's orbit radius and circumference, revealing that Earth travels nearly 30,000 meters per second. In the time it takes to watch the video, viewers have traveled millions of meters through space.

What is the constant state of Earth, even when we feel stationary?

• Earth only moves during the day.
