How many stars are there in the universe?

Question

well i wondered if there's like a program that would count them and if you know how many there are i still want the program

Answer 1

estimated at 10 ^ 22 stars, wasn't it?

Answer 2

We don't know exactly how many stars there are, nor can our telescopes pick out individual stars at intergalactic distances in order to count them. However, estimates suggest that there are a total of about a septillion stars in the Universe, accurate to within a couple orders of magnitude.

Answer 3

A careful survey done a few years ago sets the total number of stars in the *observable* universe at 70-sextillion.

Answer 4

There are more than 100 billion stars in our galaxy and there are more than 100 billion galaxies each with hundreds of billions of stars! So the total number of stars in the Universe is more than 10^22.

Answer 5

Because we don't know how far the universe reaches I think that answer may never be known, at least in the foreseeable future. Our present technology has come up with a measurable size and with that size (how far from us the most distant objects are) we can estimate how many stars but as time passes and technology grows, the size of the universe and how many stars it holds will certainly grow.

How many stars at the present? My guess is a number type we have not yet invented (like "gazillions").

Presently, I'm concerned with the 6-7,000 stars I can see without optical aid. Adding another couple of million I can see with my 10" scope brings the number way above those I will be able to observe in my lifetime.

Answer 6

JIM u are partially right,

it's there are more stars in the universe then there are grains of sand in all the DESERTS and beaches in all the world

Answer 7

One zillion.

Answer 8

There is about 3000 in the earth's sky that can be seen with the naked eye/telescope but in total there is more stars that there is blades of grass on earth.

Answer 9

Bubba and I went out on the lawn by the creek tonight to lay

down and try to count the stars so that we could be pretty certain

of our answer to your question here in yahoo questions and answers.

We took a blanket and four six packs of Coors Light Beer with us.

Bubba also brought along a couple of pencils and some paper to

make notes on our count.

Now Bubba says that the number 7 is unlucky so he doesn't use that

number when he is counting stuff, so you will have to understand that

when you see his double 8's in the counting that we did. See he

counts 0, 1, 2, 3, 4, 5, 6, 8, 8, 9 and so on. Anyhow after the first

two six packs we had been counting and started again and again

cause it is easy to loose track of your place when you take a swig

of coors. Some swigs are little short ones, you know. And some are

kinda long pulls when it goes down real good and all.

So, not wanting to drag this out any longer than normal, or get Barack Obama upset cause we didn't watch his smiling face on the television, I will cut right to the ham and salami of this answer adventure for you. Bubba and I counted more than 145 over there right by the big oak tree. We also counted at least 41 down by the creek. And, don' t let this get your goat now, there are more than 57 right over head when you lay down flat after a big pull on that Coors Light Can. They do seem to move around a bit though and it is kinda hard to keep them

to stay put long enough to get 'em counted.      

Answer 10

Wasn't it Carl Sagan that said there are more stars in the universe than grains of sand on all the beaches in the world?

Answer 11

I there are approximately 100 billion stars a galaxy, and approximately 1 billion galaxies existing, than approximately 100 zillion (100,000,000,000,000,000) stars exist. However, this is only an approximate guess, not an actual number. My guess is 500 quadrillion (500,000,000,000,000,000,000).

Answer 12

Ummm......all of them.

Answer 13

Discovery channel programmes have regularly quoted an estimated 100Billion Galaxies with an average 100 Billion stars per galaxy

Answer 100 Billion x 100 Billion thats quite a few Not sure if its an american billion or a UK billion they are different.

USA billion 10^9

UK Billion 10^12

answer is either 10^22 or 10^28 but I would go for 10^22 as previous answer  

Answer 14

more then the grains of sand on all the beaches of all the world. hun, no on can count stars. universe is infinite

Answer 15

An infinite amount.
