Solar eclipses occur whenever the Moon passes between the Sun and the Earth. If Moon's shadow obscures completely the Sun, we talk of a "total solar eclipse". If Moon is sligly farther away from the Earth, due to the fact that the Moon's orbit is not a perfect circle, then the Moon's shadow does not quite completely obscure the Sun, we talk of a "anular solar eclipse".If Moon's shadow obscures only part of Sun's disk, the eclipse is called partial.

This phenomenon can be seen about every 18 months on the Earth. However, total solar eclipses are generally observed from different regions of our planet. Thus it is likely you will have to wait a few years to see the next total solar eclipse, unless you want to travel.

The next total solar eclipse in America will be in 2024. There will be an Anular Solar Eclipse in 2023. For details of future solar eclipses please see: https://www.greatamericaneclipse.com/future/ and
