Answer:

An eclipse happens when one astronomical body blocks light from or to another.

Explanation:

The Moon moves into the shadow of Earth cast by the Sun. When the Moon passes through the outer part of Earth’s shadow—the penumbra, where the light of the Sun is only partly extinguished—the Moon dims only slightly in what is called a penumbral eclipse. When the Moon passes through the central part of Earth’s shadow—the umbra, where the direct light of the Sun is totally blocked—the lunar eclipse is considered partial if the Moon is partly within the umbra or total if the Moon is completely within it.
