How many stars are there in the sky?

Answer 1

The number of stars in the sky remains a great unknown.
Some say there are 400 billion stars in the Milky Way, although "a 50% error either way is quite plausible.

Answer 2

Stars are not spread uniformly across the universe, but are normally grouped into galaxies along with interstellar gas and dust. A typical galaxy contains hundreds of billions of stars, and there are more than 100 billion (1011) galaxies in the observable universe.

Astronomers estimate that there are at least 70 sextillion (7×1022) stars in the known universe. That is 230 billion times as many as the 300 billion in our own Milky Way.

Answer 3

The creator (NATURE ) might not know !.
But i tell you , It must be as many as the grain of sands in all the sea shores of all the continets in the world . Before you might read the answer some might have appeard new in some corner of the universe and some might have turned into black holes too.!
the sky is not what yousee . What we all sky is the space around the entire globe of earth to a distance that is indeterminable all around !

Answer 4

Since the universe is indefinite and endless in size the numbers of the stars in it is unlimited as well. But here is a thought. How do you count stars if their light takes so much time to travel to earth that by the time you see it arrive here the star might be long gone and dead in its original place. So what are we counting now?

Answer 5

The count so far says about 6 per each person on Earth or 30 Billion approximately

Answer 6

Nobody, not even the smartest scientist in the world, knows the answer to that question. But we all just stick to the theory of their being billions of stars in our sky.

Answer 7

Dear Dr. Universe,
How many stars are there in the sky?

Mary Aegerter - Uniontown, Washington


When I asked that question of Julie Lutz, a professor of astronomy at Washington State University, she said, "It depends."

If you're in a large city, you'll see fewer than 100 stars.
If you're in a dark place with no lights, like in the middle of a Palouse farm field with no moonlight, you'll see about 2,000 stars.
"But," says Professor Lutz, "that's not really how many stars there are."
You get the idea. Where you put your eyes helps determine how many stars are in your sky. Which is of course not necessarily the same as the sky.
In fact, counting the stars in the sky really means determining the number of stars in the universe, in all of space.
"All we've got of the universe is what we can observe," says Professor Lutz. And we can't observe all of space, even with telescopes. It's just too big. So we can't really count all the stars.


When it gets dark, Professor Julie Lutz and I will be ready to count some more stars. Her telescope is inside the big dome behind us. But I've got mine ready just in case.


But it's worth a guess
However, astronomers can estimate the number of stars in our own Milky Way galaxy. They combine what they know about our sun, which is actually a star, with what they know about the Milky Way.
The Milky Way, like all galaxies, is an assemblage of stars, gasses and dust. It's shaped like a pancake. But instead of being solid, the Milky Way is spiral-shaped, like the biggest pinwheel you can possibly imagine.
This huge pinwheel rotates, and the way it rotates allows astronomers to estimate how much material there is within the galaxy. Since they also know how much material is in our sun, they can determine how many sun-equivalents there are in the Milky Way by dividing the total estimated material in the galaxy by the amount of material in our sun. (And you were wondering what algebra could be used for?)

How many zeroes?
When astronomers do that division, they get 200 billion stars in the Milky Way--that's 200,000,000,000!
And the Milky Way is just one of many galaxies in the universe--one of millions. "There is no limit to the number of galaxies that we've found," says Lutz. And there's no reason to think there will be a limit to the number of galaxies, for the further astronomers look, the more they find.
The Hubble space telescope is one of the tools that is helping astronomers to see further. One of its jobs is to take pictures of one small patch of the sky outside of the Milky Way. It's dark out there, very dark. So Hubble takes a lot of pictures of that one patch. Then a computer makes a composite of these pictures, adding them together so the faint light of distant stars and galaxies is visible.
What Hubble has shown us so far is that as far away as it can see, there are more and more new galaxies. And since Hubble is not the ultimate see-the-farthest instrument, there's no way to know whether or not we'll find more galaxies as technology gets better.
So how many stars are in the sky? Use your imagination. Your guess is as good as mine

Answer 8

Good Question! Is there a number we know high enough to count them all? If you lived in New Mexico you would know that there are too many to be counted!

Answer 9

why does it matter? jk jk...

real answer: over 100 billion but we have no idea anyway since we can't see all of them presently due to the fact that their light sometimes takes over 200 years to reach us, so they could've died and we wouldn't know at all. plus, there are whole universes out there and galaxies that we can't see at all and people can be living there with advanced technology or living like we did in the 1600's...cavemen even. we have no idea about most things in the universe....so....chill because your real question is "how many skies are there?"

dun Dun DUUUNNNN

Answer 10

Infinite stars
