Stars and the galaxy???

Question

Well when you look up at the stars they look tiny but are actually bigger than our planet...Earth. Then I was thinking if you were on one of the stars and looked down to Earth would it just look like a tiny spec like we see other planets like? x

Answer 1

Actually, if you were on one of the stars, you wouldn't be able to see the Earth because it is so small and the stars are so far away.

Aside from the Sun, the next closest star is about 4.2 light years away. At that distance, the only way you could detect the Earth is if you had an instrument that would detect the difference in light output by our Sun as the Earth passed between you and the Sun. You'd have a much better chance at picking up Jupiter that way, though.

Hope this helps.

Answer 2

You wouldn't see the Earth from an extra-solar star. You wouldn't see it from our star, it's just too small and has no light of its own to shine with. The Earth reflects the sunlight really well because of all the water on its surface but the fact remains that it's really, very very small.

We are currently trying to find extra-solar planets but so far the ones we've found have been about the size of Jupiter, which is much, much bigger than the Earth.

Answer 3

Actually, if you were on one of the stars, you'd be vaporised...

That aside, you wouldn't even as much as see the Earth, and only with a bit of luck MAYBE make out Jupiter in its orbit around the sun.

the reason why stars look like little dots is something quite normal - it has to do with physics. Something to do with distance and volume of the object. Look it up, it's interesting read.

Answer 4

You have to get a scale of things out there.

The nearest stars are thousands of times further than the furthest planet in our system. That is, Alpha Centauri, the nearest of all stars to us is about 8000 times as far as Pluto.

Most of the stars you see in the sky are many times further still.

If you went to Alpha Centauri, the sun would look like a very dim star - just visible to the naked eye.

The planets would be undetectable with the technology we have at present.

Answer 5

first thing: you will not look DOWN to earth from any other star or even our moon. its strange but even from moon you will have to look up to look at the earth. And no you cannot see the planet earth if you go to one of those starts because starts are like sun; they glow and thats why we can see them. Planets and their moons only reflect light of our start which is the sun. Are you with me?

Answer 6

If you were on another star, you would burn up so fast, your nervous system would not have time to alert you to the fact.
The earth would be much too small to make any impression on you at that distance even if alive. ;-)

Answer 7

We are but a speck of dust, insignificant. Download the program "CELESTIA" it is free, and will open your eyes.
