How many stars are there in the sky???

Question

How many stars are there in the sky???

Answer 1

Billions of Stars in the milky way with a black hole for a center and Billions of Galaxies in our Universe!!!!!!! So.......Billions among Billions!!!!!

Answer 2

it unknown but there are lot of stars in the sky billions and billions  of stars but get this as u know there are so many starts that the start don't even fill a quarter of the universe

Answer 3

There are about 73 sextillion stars that we can detect with our current technology.  That doesn't mean that we can see all of them.

Answer 4

a lot.

Answer 5

TOO many to count.

Answer 6

They're not really "in the sky" ... they're scattered all over our galaxy and in other galaxies all through the universe.  

Do you want to know how many, total, stars exist or do you want to know how many stars are visible from Earth?  

If you want to know how many are visible from Earth, do you mean from the entire planet or from your portion of the night sky?  

If you mean from your portion of the night sky, do you mean during the course of an entire night or just during a brief period?  

It's not possible to give an accurate number of how many stars exist in our universe, because we haven't developed scopes that can see that far yet.  For a good grasp of just how large the scales involved are, take a look at some of Hubble's deep field images.  

Below is a link to the Hubble Ultra Deep Field.  Every blob of light in the picture is an entire galaxy!  Puts things in perspective doesn't it?  <smile>

Answer 7

Do you mean actually, or do you mean visible to the unaided eye?

Our galaxy has about 200 billion stars, and there an estimated 100 billion galaxies, so that is a lot of stars.

But not all of them (not even all in our galaxy) are visible from Earth.

The unaided human eye can see down to apparent magnitude 6.5 from a dark location, and in our skies there are about 6000 stars of that magnitude or brighter.

But only half are visible in each hemisphere, and only half of those are visible in a night (the others are in the sky at the same time as the sun).

So in theory the human eye could see a total of about 3000 stars from a clear dark location throughout the year, but the atmosphere absorbs some starlight and that reduces the number to between 1500 and 2000 (in the center of a city as few as 200 to 500, due to light pollution).

On one night, without any aids, from a dark location with clear skies, you might see at most 1000 stars throughout the entire night.

Answer 8

The number of stars you could see with the naked eye on a perfectly clear, very dark night is about 9,500. All of those stars are in our own galaxy, the Milky Way (http://www.kstrom.net/isk/stars/stareye....

Some years back a careful sky survey was conducted and a research team said that there about 70-sextillion stars in the entire observable universe (http://www.abc.net.au/science/news/space...

Answer 10

Depending on where you are (how much light pollution is around you) and how good your eyes are, you might see up to 6000 stars with your naked eyes.   To do this, you'd have to travel to the Southern Hemisphere if you live in the Northern one (or vice-versa), and you'd have to count over a period of time, because on any night, you only can see a fraction of the stars visible at other times.   If you live in downtown London, New York, Tokyo, Hong Kong or any other big city, you might not be able to see more than a few.

The other answers are much closer to the actual number of stars that are out there, but you can't see them without some aid (binoculars, telescope, camera, etc.)  

Most days you can see just one, our nearest star, the sun.  Most nights you can see several thousand.  When I look through the eyepiece of my telescope at, for example, the great cluster (M13) in Hercules, high in the sky these nights, I can see many hundreds of thousands (I've not counted them, though), and these are just a cluster that is part of our Milky Way galaxy.

Answer 12

30 Billion Trillion. That's in the VISIBLE universe. A typical galaxy has 100 billion stars and there are 100s of billions of galaxies.

But on a dark night in the country you can see with your eyes maybe 4000-5000 stars.

Answer 13

300 Billion cubed, ok fine there is alot less than that but still too big of a number to imagine in our tiny useless heads.

Answer 14

More than the number of grains of sand on earth.

Answer 15

a result says that 10 rest to 11 stars in one galaxy and 10 rest to 11 galaxies in the universe.

That means in the whole cosmos there r 10 rest to 22 stars.

Now find which star is ur twinkle little?????

Answer 16

On a clear night away from city lights, you can see...   Well, it depends on how good your eyes are.  The average person can see about 2,200 stars at any one moment from that dark spot out in the desert or on the ocean.  You have to be completely free of extraneous light, so most Americans have never seen this, and they never will.

When an earthquake knocked out all the lights in Los Angeles in 1994, people were calling the police asking what all those little lights in the sky were.  That's how separated we have become from the basic nature of our world.  Most Americans--and urban dwellers anywhere on earth--have never seen a clear, dark sky full of stars.  There are only a few places left.

If you wanted to imagine being able to see all the stars that can be seen with the naked eye from everywhere on earth at once, it would be around 10,000 stars.

If you consider "the universe" to be all of the universe that we know about and can measure and detect, it includes trillions of galaxies each containing trillions of stars (on average).

It has been calculated that there are in total about 70,000,000,000,000,000,000 stars in the detectable universe.  As to what is really there?  We have no way of knowing.

Answer 17

Visible to the naked eye in an area with little light pollution there are about 9000 stars visible.

So far astronomers estimate that there are around 100 billion galaxies, with an average of 100 billion stars per galaxy. So that means there are some where in the area of 100 billion, billion stars in the universe. To put that into writting that means there are approximately 1000000000000000000 stars in the universe (hope I counted enough zeros).

I didn't! 100 billion x 100 billion is equal to 10000000000000000000000
