The first solar eclipse of 2021, an annular solar eclipse, occurred on June 10. A complete solar eclipse, as in when the Moon fully obscures the Sun, happens as a result of the Moon is about 400 occasions smaller than the Sun, but in addition 400 occasions nearer, giving each the celestial our bodies the identical obvious dimension within the sky. A partial solar eclipse happens when the Moon's orbit isn't fully aligned with that of the Sun, thereby leaving a sliver of the solar halo.
