How Do We Know How Old the Sun Is?

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.
