About this episode

This episode explores the true size of the Moon and its significance in relation to Earth and the solar system.

The Moon looks small in the sky… but its true size might surprise you. In this episode, we take a closer look at Earth’s only natural satellite — the Moon — and explore just how big it really is. From its diameter and mass to how it compares with planets and other moons in the solar system, the numbers tell a much bigger story than what we see from Earth. How does the Moon compare to Earth? Why does it appear larger than it actually is? And what would happen if it were any bigger… or smaller? We break down the scale, the science, and the surprising role the Moon plays in shaping tides, stabilizing Earth’s rotation, and even making life possible. Because sometimes… the things that seem small are anything but. Become a supporter of this podcast: https://www.spreaker.com/podcast/kurzgesagt-podcast-science-revealed--6600013/support .
