How it is different from total or partial solar eclipse?
When it comes to total solar eclipse, the moon totally covers the sun; it occurs when the new moon comes between the sun and the earth and casts the darkest part of its shadow, called the umbra, on earth.
During this, it becomes dark like an evening with no sunlight. The next total solar eclipse is likely on December 14 this year.
Now, talking about partial solar eclipse, the moon crosses in front of the sun off centre, leaving a crescent-shaped portion of the sun visible. This happens when the moon comes between the sun and the earth but the moon only partially covers the sun’s disk.
During this, the three celestial body does not come in straight line. The moon casts only the outer part of its shadow, called the penumbra, on earth.
