We guess.
Really. There's no way to actually COUNT the stars in the Milky Way; the small ones are too small and dim to see if they are more than a few dozen light years away. So we make estimates, which are little better than guesses.

What is out of space when not in space anymore?
well the universe is endless, but the universe is made up of many galaxies, and galaxies are made of planets and stars and dust etc.
Explain how all galaxies are similar?
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
What is thev connection between universestar and galaxy?
The universe comprises all matter in space. This includes a very large number (200 billion to 2 trillion) galaxies. Each galaxy comprises a very large number of stars: our contains 100 thousand million stars.
Is it true Our galaxy contains many billions of universes and each universe contains many billions of stars.?
No. The universe contains billions of galaxies including our own, and each galaxy contains billions of stars.
How many stars out there?
trillions If our galaxy with 2*1011 (two hundred billion) stars is an average size galaxy. and there are as many galaxies in the Universe as there are stars in our galaxy, then there are possibly 4*1022 stars in the Universe. But that is just a guess. There are most certainly more than 1018 stars.
What do galaxy's have in common?
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
How many star make up our universe?
The amount of stars in the Universe is not know. The visible Universe has several hundred billion galaxies, each of which, on average, has perhaps a hundred billion stars or more. Even the exact shape of the Universe is an area of current research. In any case, it does seem that the Universe is much bigger than it was believed a few decades ago.
How many suns are in a galaxy?
Our sun is one of between 200 and 400 billion stars in the Milky Way galaxy. There are literally untold billions of galaxies in the observeable universe. Our sun is just another star among billions of billions other stars. Some of which are known to have planets orbiting them.
How many galexy are there?
We don't actually know - because we cannot see the universe beyond a certain point due to the fact that we are in it. We have named the cluster of galaxies we are in the Virgo Cluster but there are many other clusters and lone galaxies as well. So we'll probably never know that answer!
How many planets does the universe have?
No-one can possibly know for sure, but the answer is probably billions. There are hundreds of billions of stars in our own Milky Way galaxy, many of which have solar systems of their own, and as many galaxies in the Universe as there are stars in our own galaxy (and the Milky Way is by no means a particularly large galaxy, just of average size). If you take all of this into account, the number of planets likely to be in the universe would be many billion.
How many galaxies are there in your universe?
There are an estimated 1011 (100 billion) galaxies in the observable Universe. It is not known how much bigger the Universe is, compared to the observable part.
How many galaxies mare in the universe?
500
