How many stars within 50 light years from earth?
According to SIMBAD, ~970. But there's a lot of stars within 50 light years whose distances aren't known. There's quite a few stars within 50 light years. To get a good estimate, we should consider how many stars within 20 light years, and go from there. The nearest 25 light years are really well catalogued, and the current census is 200 stars. Now, through knowledge of Geometry, one can say that if you multiply the radius of a 3D shape by a number, x, the volume will increase by the x^3. Why 3? because it's a 3D shape. So we double our sphere from 25 to 50 light years. So thus the volume increases by 2^3 = 8 times! So there are 8 times as many stars within 50 light years as there are within 25 light years. 200 * 8 = 1,600 stars (estimate).
How many light years away is Sirius the stars?
8.6 light years
How many light years are there in stars that are in your sky?
It varies widely, the closest star other than the sun is just over 4 light years away, but most of the stars we see are a few dozen to a few hundred light years away.
How many light years away is the little dipper?
i cant say because the little dipper is made op of many differt stars and alls 7 stars r different light years away. 4 example, the star kochab is 126 light years away and the star pherkad is 480 light years away.
How many stars are within 12.5 light years of the earth?
You can check the Wikipedia article "List of nearest stars". Note that it is quite possible that not all stars up to that distance have been discovered, since red dwarves and brown dwarves are quite difficult to detect.

How many stars within 16 light years of your solar system?
49 including our sun.
How many light years away is Sirius the stars?
8.6 light years
How many stars are 1 light year from the stars?
I assume that you meant to ask "How many stars are 1 light year from the earth?"The answer is none.The closest star to us is Alpha Centauri which is 4 light years away.Unless you count our own sun which is 8 light minutes from the earth.If you meant to ask "How many stars are 1 light year from any other stars?"Then the answer is very many.There are many places within our Milky Way galaxy where stars are close together, especially near the center of the galaxy.

How many years does starlight travel?
It depends on the distance of the star to Earth. The distance to the star in light years is the number of years the light took to get here. Most of the stars we see at night are within a few hundred light years of Earth. The closest star other than the sun is about 4.2 light years away.
How many stars in a galaxy or cloud at what per light year?
1.5 billion stars per 1000 light years.
