Lunar Eclipse and Solar Eclipse

Lunar Eclipse

Lunar eclipse often happens if Moon is in the position of opposition and lies in one knot so Earth’s umbra covers Moon, then it happens total lunar eclipse. On the contrary, if the moon lies around knot, so he Earth’s penumbra covers Moon, then it happens penumbra lunar eclipse.

Basically, the lunar eclipse is divided into three kinds, those are penumbra, partial and perfect lunar eclipse.

Solar Eclipse

There are three kinds of solar eclipse, those are as follows:
1. Total Solar Eclipse, it happens as the cause of core shadow of the moon falls to the Earth.
2. Partial Solar Eclipse, it happens if that covers Earth is only penumbra.
3. Ring Solar Eclipse, it happens if the Umbra of the Moon does not arrive to the Earth’s surface and sun appears as white ring around black ball.

The longest solar eclipse happened in 1955, it happened for 7.2 minutes that passed Sri Lanka, Thailand and Philipine.
