How Do We Know How Old the Sun Is? The Royal Observatory, Greenwich, and animation studio Beakus join together to explain how Kepler and Newton’s laws help us figure out the weight of the sun, how the age of our solar system can be calculated by studying meteorites, and how that data helps us determine the sun’s age.

Previously from the Royal Observatory Greenwich, Measuring the Universe, and more videos about the sun.

This Webby award-winning video collection exists to help teachers, librarians, and families spark kid wonder and curiosity. TKSST features smarter, more meaningful content than what's usually served up by YouTube's algorithms, and amplifies the creators who make that content.
