Eclipses
During every eclipse there are 2 important shadows that are cast. They are called the umbra and the penumbra. The umbra is the shadow that get smaller the farther away it gets from the sun. The penumbra is the opposite because the shadow gets larger the farther away it gets from the sun. Not every eclipse is the same because there is 3 types of solar eclipses and 3 types of lunar eclipses.
SOLAR
1) The first type of solar eclipse is the total eclipse which is when the moon is
completely blotted out by the sun.
2) The second type of solar eclipse is a partial eclipse which is when the moon covers only part of the sun.
3) The third type of solar eclipse is an annular eclipse which is when the moon only darkens the middle of the sun.
LUNAR
1) The first type of lunar eclipse is a total eclipse which is when the entire moon passes through Earth's shadow.
2) The second type of lunar eclipse is a partial eclipse which is when
3) The third type of lunar eclipse is the penumbral eclipse which is when the moon is completely inside the Earth's penumbral cone.
Eclipses can actually happen on other planets that have moons. Eclipses can happen every other month but they can only be seen in certain places. We know when the next eclipses are going to happen and where they will be visible because astronomers can predict eclipses. When there is an eclipse there is an occultation which is a blocking action.
