Speed of the Earth

The video explains Earth's constant movement through space, detailing how astronomers calculate its speed. By observing celestial objects, they determine Earth's orbit radius and circumference, which is approximately 940 million kilometers. Earth completes this orbit in one year, translating to a speed of nearly 30,000 meters per second. Despite feeling stationary, viewers travel millions of meters through space during the video.
