Lunar Eclipse

“What is a Lunar Eclipse?” asked the inquiring student.

Wally Wolf’s Answer:

A lunar eclipse occurs when the Earth's shadow falls on the moon. Lunar eclipses occur, on average, about every 6 months

Total Eclipse - When the entire moon enters the Earth's umbra (the darkest part of its shadow), this is called a total eclipse.

Partial Eclipse - When only part of the moon enters the Earth's umbra, this is called a partial eclipse.

How long do they last?

Duration of Lunar Eclipses

During an average total lunar eclipse, the moon is within the Earth's umbra for about an hour. This is called totality.

Lunar Eclipse Definitions

Earth - the planet on which we live.

Moon - the natural satellite of the Earth.

Penumbra - the area in which the shadow of an object (in this case, the Earth on the moon) is partial.

Sun - the star in our Solar System.

Umbra - the area in which the shadow of an object (in this case, the Earth on the moon) is total. When the entire moon is in the Earth's umbra, we experience a total lunar eclipse. When part of the moon is in the Earth's umbra, we experience a partial lunar eclipse.
