A total solar eclipse is visible from Earth. However, the region of the Earth that is able to see a specific total eclipse is relatively small. Typically, such an eclipse's path is only several hundred kilometers wide.

Approximately every 18 months, a total eclipse appears when the orbits of the moon and Earth line up so that the moon conceals the sun. When an eclipse occurs, a cone-shaped shadow of the moon, the "umbra," is cast upon the Earth, blocking out sunlight. At this point, all that is visible is the sun's corona, which is the light from the star's outer atmosphere. Total eclipses may last for more than seven minutes, but most are shorter.
