Why the size of the shadows of the SUN, MOON and EARTH are same size?

Question

Why the shadows of Moon, Sun and Earth are same size, these are same size and that's why the full eclipses happens. Anybody know the reason?

Answer 1

They are not the same. During a full solar eclipse, the moon's shadow is only a spot on earth because the moon is much smaller than the earth, you have to be inside that spot on earth to see the full solar eclipse.



During a full lunar eclipse, the earth's shadow covers the entire moon, and you don't see the moon no matter where on earth you are.

Answer 2

Not magic. Simple Physics. The Sun is larger than the moon, but is so far away it looks the same size. Earth is at the focal conjunction of these two bodies and that is why total solar eclipses are possible. The earth's shadow on the moon during a lunar eclipse is seen in two phases, the umbra and the penumbra.

Answer 3

They are not the same size at all. In fact, the size you see varies widely, depending on the angle of the earth, your position on the earth, and the distance of the Sun and Moon from us. That's why sometimes the Sun looks like it's as big as a planet sometimes, and other time it's only as big as a push-pin.



The reason why you think the shadows are about the same size is because they are always very small compared to the size of the actual planet, moon or star. The Sun is much, much larger than the moon, but it's also a lot further away.

Answer 4

The shadows the create during a full eclipse are basically because the distance they are apart, the sun being the largest, and being so far away, it apears to be about the same general size as our moon. So when the moon gets between the sun, its able to block the suns light.

Answer 5

During a lunar eclipse, when the earth blocks out the direct light of the sun, the moon appears reddish because the earth is blocking the direct sunlight that we are accustomed to seeing reflected off the moon brightly. The moon is still visible because the sun illuminates so strongly that the light that travels past the earth is still strong enough to make the moon visible.



During a solar eclipse the moon passes in front of the sun and appears to us to have blocked out it's light nearly entirely and on earth everything looks as if it's twilight not unlike what it would appear to be if you were standing on the moon during a lunar eclipse.



As for the fact that the "disk" of the moon and the "disk" of the sun as it appears to us in the sky being of such an astounding fit in the sky. Well, that's still a great mystery isn't it. Something that has inspired plenty of legends, fears, and celebrations in the past. Today we seem to lack to basic natural wonder when it comes to these things it seems.

Answer 6

the moon doesn't make a shadow as big as the Earth, which is why we can still see the Sun around the moon in an Eclipse

Answer 7

Hey buddy. Y is it an insult to me? you wrote that on my questions.



And the shadows are not of same size just that from a particular angle on earth (in case of solar eclipse) we see the moon completely covering the sun.



And the doubt that why it (moon's shadow) does not exceed the suns area from where we see is mere coincidence of astronomical distances.



You can post your clarification on any of my questions.

Answer 8

They are not the same size. That is why on any given eclipse day there is a full eclipse in some places and only a partial in others.

Answer 9

i think it has something to do with this. how does the moon appear to be the same size as the sun? because the sun is a thousand times bigger but a thousand times further away at the same time. it may not be a thousand but something like that you get the idea

Answer 10

The shadows are not the same size

Answer 11

no, the shadow of the three differs.The shadow of the moon covers the sun when we r looking from a particular point.But that region where the sun is covered by moon,will be very small.

Answer 12

They are not the same size. They only appear to be, due to relative distances.

Answer 13

you are wrong.. they are not of same size..we cannot see earth's shadow..full eclipse do not occur due to shadows.. it is due to eclipse we see shadows.

Answer 14

they are not the same size

Answer 15

We are like toys in a childs toy box. It depends on how far back you hold the flashlight...
