        Where Are We? Ch. 3: Solar Eclipse | Genius by Stephen Hawking

        In this clip from Genius by Stephen Hawking, learn how to work out the distance between the Earth and the sun. Using to scale models of the Earth, Moon, and sun, the team of volunteers must work out the distance between the Earth and the sun. The volunteers already know the distance between the Earth and the Moon. The key to answering the question will be to create a solar eclipse where the moon passes in front of the sun. When this happens the moon and the sun are seen to be the same size. The team will have to travel a long distance to allow their tiny scale moon model to eclipse the gigantic sun but when they do they will be able to calculate the distance between the Earth and the sun.
