The next penumbral lunar eclipse: May 5-6, 2023
An eclipse of the moon can solely occur at full moon, when the sun, Earth and moon line up in space, with Earth within the center. So at such instances, Earth’s shadow falls on the moon, making a lunar eclipse. Lunar eclipses occur a minimum of two times to a maximum of five times a yr. As a matter of reality, there are three sorts of lunar eclipses: total, partial and penumbral.
The three forms of lunar eclipses
In a total eclipse of the moon, the internal a part of Earth’s shadow, known as the umbra, falls on the moon’s face. Then at mid-eclipse, all the moon is in shadow, which may appear blood red.
Subsequent, there’s a partial lunar eclipse, the place the umbra takes a chew out of solely a fraction of the moon. The darkish chew grows bigger, after which recedes, by no means reaching the total phase.
Lastly, there’s a penumbral lunar eclipse, when solely the extra diffuse outer shadow of Earth – the penumbra – falls on the moon’s face. In reality, this third type of lunar eclipse is far more refined, and far more tough to look at, than both a total or partial eclipse of the moon. That’s as a result of there’s by no means a darkish chew taken out of the moon, as in a partial eclipse. So the eclipse by no means progresses to achieve the dramatic minutes of totality. And at finest, at mid-eclipse, very observant individuals will discover a darkish shading on the moon’s face. Others will look and see nothing in any respect.
In accordance with eclipse professional Fred Espenak, about 35% of all eclipses are penumbral. One other 30% are partial eclipses, the place it seems as if a darkish chew has been taken out of the moon. And the ultimate 35% go all the best way to changing into total eclipses of the moon, a phenomenal pure occasion.

Backside line: There are three sorts of lunar eclipses: total, partial and penumbral. A penumbral eclipse could be very refined. At no time does a darkish chew look like taken out of the moon. As an alternative, at mid-eclipse, observant individuals will discover a shading on the moon’s face.
