Because they are so far away. Light travels at approximately 186,000 miles per second. Our nearest star Alpha Centauri, is about 4.5 light years, so it takes light (eg the Stars glow) four and a half years to reach us.
A rough distance to Alpha Centauri is.....
26,000,000,000,000 - 26 Trillion miles... and that's our nearest!!

∙ 14y agoAh, Olbers' Paradox. If you think the universe is infinite, then it's a real puzzler. However, the visible universe isn't infinite; we can't see anything more than about 13 billion light-years away. In the part we can see there aren't enough stars to light up the entire sky at night.
Wiki User
∙ 13y agoIt is not known that there are infinitely many stars, just a very, very large number of them. Since stars are gathered into clusters called galaxies, they are not evenly spread out. We can only see out to about 14 billion light years, and in this space there is not an infinity of stars. Recently the Hubble was aimed at the blankest area of sky they could find; an area with nothing visible in it by conventional telescopes. Hubble saw untold numbers of galaxies never seen before. There is no reason to think the same sort of thing isn't in every direction. But that is not the same as "infinite".

∙ 10y agoLight travels at a speed of about 186,300 miles per second. This is still a finite speed, and so the farther away a light source is, the longer it takes the light to reach us. The stars are so distant that, even moving at such incredible speeds, the light takes years to reach us, though not necessarily 1000 years.

∙ 12y agolight takes approximately 8 minutes to travel from the sun to the earth. even though it is traveling extremely fast, the earth is about 93million miles away from the sun, so if you think about it 8 minutes is pretty quick
Wiki User
∙ 11y agoBecause all of the other stars are farther from the Earth than the sun is.
The next nearest star is about 265 thousand times as far from us as the sun is.
So light from that star takes 265,000 times as long to reach us as sunlight does.
(4.2 years instead of 81/3 minutes.)

∙ 11y agoThe star nearest to Earth excluding the Sun is Proxima Centauri, and it is 4.2 light years away. However, it is so small that it is too faint to be seen with the naked eye.
Wiki User
∙ 13y agobecause they r so far away...it takes the sun's light 8 minutes to reach earth.

Why do we see star at night?
we only see stars in the sky at night because in the day it is light because of the sun. The stars are very light but the stars can not be seen because of the sunlight. So when it is pitch black you can see the stars so the stars sparkle in the sky without no light showing so its just the stars and the moon lighting up the world!
