- Hey, smart people, Joe here.
The sun is humongous, 10 times the size of anything else in the solar system.
Uh-oh.
(upbeat music) And 100 times the size of earth.
But earth is part of a lucky cosmic coincidence.
Our moon is 400 times smaller than the sun, but it's almost exactly 400 times closer to us.
This means to us here on earth, they look almost exactly the same size in the sky.
Because of this coincidence, every once in a while, our tiny little moon, even though it's 400 times smaller than the sun, crosses in front of it and blocks its light from reaching earth.
A solar eclipse.
On April 8th, that's gonna happen right here.
