According to the part of the solar disk that is covered by the lunar disk, it is distinguished:
- Total eclipse. When the moon completely covers the sun. This phenomenon is quite rare, and is only seen in a certain area of the Earth every 200 to 300 years. In nearby areas, this eclipse looks like a partial eclipse.
- Partial eclipse. Only a part of the Sun is hidden.
- Annular eclipse. It occurs when, due to the position of the Moon, it does not completely cover the solar disk and a ring of the solar disk is seen.
Since the Earth is quite a bit larger than the Moon, it is easy for lunar eclipses to look like total eclipses from many parts of the world.
For a lunar eclipse to occur, there must be a full moon, and for a solar eclipse to occur, there must be a new moon. Since we have a full and new moon every month, why isn't there a lunar eclipse and a solar eclipse every month?
