Answer» Answer: Solar Eclipse is also known as the eclipse of the sun, it occurs when the MOON comes in between the sun and the earth. As a result, the moon blocks the light of the sun from reaching the earth's surface and CASTS a shadow on it. This occurs on a NEW moon phase. We can observe up to 5 solar eclipses per year.
