Only three humans have ever witnessed an eclipse of the Sun by the *Earth*. It happened while the Apollo 12 crew was returning home from the Moon, on November 21, 1969.

Fortunately, the astronauts filmed the moment so you can share in the experience.

Earth eclipsing the Sun happens many times a day for astronauts when the #ISS flies into Earth's shadow during part of its Low Earth Orbit.

Strictly you cannot even compare a solar eclipse by the Moon and one by the Earth as equivalent as, by happenstance, the angular diameter of the Moon and the Sun at lunar distance is almost exactly the same meaning that phenomena such as Bailey's Beads are not visible when the Earth, with its much larger angular diameter, eclipses the Sun.

To do it right, you need to watch Earth pass in front of the Sun from a distance of 850,000 miles. I'm putting it on my to-do list.
