The video explores the transition from the geocentric model, where Earth was believed to be the center of the universe, to the heliocentric model proposed by Copernicus, which placed the Sun at the center. It highlights the contributions of Kepler, who introduced elliptical orbits, and Galileo, whose telescope observations supported the heliocentric model. Despite initial resistance, these ideas eventually led to our modern understanding of the solar system, where both Earth and the Sun orbit a common center of mass.

At what speed is Earth orbiting the Sun?

• 107,000 kilometers an hour

• 50,000 kilometers an hour

• 150,000 kilometers an hour

• 200,000 kilometers an hour
