This a natural thing that sun make it so we will talk about it cause everyone know the eclipses and want to know..,

Why Eclipses Happen?

It's an important question and we will answer about it here, first,you have to know that to see a total soalr eclipse,you have to be in just the right spot on the earth.

When you look up in the sky at the sun and the moon,you notice a starnge coincidence-both look the same size in the sky.both the sun and the moon look about one-half degree in diameter.

Now,they're not really the same size.The sun diameter is actually 400 times the moon's diameter.but,you must also take into account that the sun is also 400 times further away from the earth ,reducing its apparent size to the same at the moon's.

Because of this relationship,when you are standing on the earth,looking up at the tow,you must be very in limited zone to see the moon cover the entire face of the sun.if you were to move little north the sun would peek out over the top of the moon;a little south,and the sun shines past the southern limp of the moon.the much is so good that the "the path of totaality" is never more than 167 miles in diameter,and is usually less.

this means that very few people have seen a total eclipse because the shadow only covers a very small area on the erath.





The diagram shows a side view of the alignment.From any where in grey penumbra,you will see some part of the sun shining from behind the moon.
the penumbra is the area of partial eclipse.only from within the tiny area where dark umbra touches the earth will you see the sun completely coverd and witness a total eclipse.
