A solar eclipse occurs when the Moon comes between the Sun and the Earth, blocking the Sun from our view. In a total solar eclipse, the Moon blocks out the Sun from our view completely. In a partial eclipse, however, a part of the Sun is visible. During an annular eclipse, we can see a small ring of the Sun glowing around the Moon. When the Moon is nearer to the Earth it appears larger and therefore covers the Sun completely, although it is actually much smaller than the Sun. However, in an annular eclipse the Moon is too far away from the Earth to block the Sun out totally and therefore a ring of sunlight is seen.
