Solar System and Planetary Motion

The video explores the history of astronomy, focusing on the shift from the geocentric to the heliocentric model, as proposed by Copernicus and supported by Galileo's observations. It explains the structure of the solar system, the concept of orbits, and highlights key planets like Jupiter, Mars, and Saturn. The video also discusses the Sun's central role and gravitational influence in the solar system. It concludes with a learning objective related to the apparent size of celestial bodies and offers additional educational resources.
