An eclipse happens when the moon, sun, and Earth falls on a straight line. There are two main types of eclipse: a lunar and solar eclipse.
A lunar eclipse happens when the Earth is between the sun and the moon, and this occurs during a full moon. There are two types of lunar eclipse: A total lunar eclipse occurs when the moon is fully within the Earth's umbra or darker side of the Earth, while a partial lunar eclipse happens when the moon is only partly in the umbra.
A solar eclipse is followed by a lunar eclipse fourteen days later and vice versa. There are two types of solar eclipse: A total solar eclipse is where the moon's umbral shadow falls on Earth. Its like the entire disc of the sun is blocked by the moon. While observers located on the penumbral shadow (the lighter side of the Earth) see a partially blocked sun called the partially solar eclipse.
