There are three different types of solar eclipse: Partial, Annular, and Total.
A partial solar eclipse is when the Moon does not line up completely with the sun.
An annular solar eclipse is when the Moon and the Sun are in line, but either the moon is further from Earth or the Earth is closer to the Sun. In this situation, the apparent size of the Moon is smaller than that of the Sun, which then creates a bright ring surrounding the darkness of the Moon.
A total eclipse is when the moon completely covers the sun.
