Solar eclipses of the coming year 2021 will occur on 10 June while the last will occur on 4 December 2021.
Solar eclipses are natural phenomena that result from the Sun’s light, not reaching the Earth. This typically happens due to the Moon coming between the path of the Sun and the Earth.

Our natural satellite casts a shadow onto our planet during a solar eclipse. Depending upon the light that gets blocked, there are various kinds of solar eclipses. When the Earth and the Moon are in a direct line, only a tiny part of the world will be able to see the sunlight and the whole sky turns dark although it is daytime.
When the Sun, the Earth and the Moon are not precisely lined up, it is a partial solar eclipse. Therefore, the Sun appears to have a dark shadow on only a tiny part of its surface. The last that occurs is the annular solar eclipse in which the Moon is farthest from Earth. A ring of light is created around the Moon instead of blocking the Sun’s light.
In the year 2021, we are going to see two solar eclipses. Here are the dates, timings and other details about the events:
