They happen when an annular eclipse turns into a total solar eclipse. An annular eclipse of the Sun can only take place when the Moon is at apogee or when its orbit is farthest from the earth.
Partial: Partial solar eclipses happen when the Moon does not completely cover the Sun's disc and casts only partial shadow on Earth.Īnnular: Annular solar eclipses occur when the Moon's disc covers the center of the Sun's disc, leaving the Sun's outer edges uncovered. A total eclipse of the Sun can only take place when the Moon is at perigee or when its orbit is closest to the earth. Total: A total solar eclipse takes place when the Moon completely covers the Sun and casts its shadow on Earth. The following list outlines the 4 types of solar eclipses that are determined by what part of the Moon's shadow falls on the Earth: This can only happen during the new Moon phase. For a solar eclipse to take place, the Sun, Moon, and Earth must be aligned in a perfect or near perfect straight line, an alignment that astronomers call syzygy. Typically the Moon only partially blocks the Sun’s light during an eclipse, however occasionally the Moon completely blocks the Sun, causing what is called a total solar eclipse.

Only for the ~2 minutes during totality it is safe to look at the corona with no protection. Even when 99% of the Sun is covered by the Moon you can still damage your eyes. You can permanently damage your eyes by viewing the eclipse before or after totality.
