Solar eclipse

This animation illustrates a total solar eclipse as the umbra of the Moons shadow passes over a narrow region on the surface of the Earth. Not shown is the penumbra, which will cause a partial eclipse on either side of the path of totality. Distances are not to scale, and we have idealized the illustration by fixing the Earth in space relative to the Sun. In reality, the Earth will be in motion around its orbit as the Moon moves around the Earth.
