There are three types of lunar eclipses. They are the total, partial and penumbral.

A total lunar eclipse occurs when the entire Moon passes through the Earthís umbra shadow. This total lunar eclipse will show in deep orange colour. Refer to the picture below.

A partial lunar eclipse occurs when a portion of the Moon passes through Earth's umbral shadow. Depending on the size of the eclipse, a dark red or rust colour, or simply a charcoal grey may appear on the shadowed portion of the lunar surface. This is due to the sharp contrast between it and the brilliant part of the Moon that remains outside the umbra. We can expect a similar visual effect during the partial phases before and after a total lunar eclipse.

*A Penumbral Lunar Eclipse


A penumbral lunar eclipse occurs when the Moon passes through Earth's penumbral shadow. In this eclipse, none of the lunar surface is completely shaded by Earthís umbra. Instead, only the slightest dim near the lunar limb closest to the umbra can be seen. Indeed, only when at least half of the Moon enters the penumbra, then we can see the penumbral lunar eclipse.

During a penumbral eclipse, an astronaut on the Moonís surface would see a partial solar eclipse, with the Earth blocking a portion of the Sunís disk ; During partial and total lunar eclipses, he would witness total solar eclipses, with the Earth masking the entire Sun, including the corona, at maximum.
