Solar Eclipse Educational Video


 
 
 
What is Solar Eclipse ? An eclipse of the sun occurs when the moon revolving in its orbit around the earth comes between the sun and the earth. The moon blocks the light of the sun and a shadow of the moon is cast over the earth's surface..

How does the moon block the sun?
By a fortunate coincidence, the sun's diameter is 400 times larger than that of the moon, and at the same time, it is 400 times as far away. From where we are, this creates the illusion that they are the same size. If we look through a filter at the sun, it looks exactly like the moon on a full moon night. When the moon passes in front of the sun, the shadow falls on the earth and it appears to exactly cover the sun's disc. This is what a solar eclipse is - a shadow.
