How many suns in our universe?

Question

How many suns in our universe?

Answer 1

Scientists have estimated that there are roughly 70 trillion galaxies in the Universe. If we assume that each galaxy has about 15 billion stars, which is a pretty reasonable average, then the Universe has about 10^24 stars (that's 1 000 000 000 000 000 000 000 000, or a million million million million, stars). This value could be off by at least an order of magnitude, but it's still accurate enough to be a useful estimate for many purposes. Keep in mind that a relatively small fraction of these stars are like the Sun. The majority of them are red dwarf stars, much smaller and cooler than the Sun.

Answer 2

Exactly a whole bunch...

No seriously; given that there are about 400 billion galaxies with up to a trillion stars in each one, that puts it in the ballpark of 400,000,000,000,000,000,000,000,000.  (Give or take a million billion.)

Answer 3

One Sun, ours. Countless stars.

Yes our sun is a star but no other star is our sun;)

Answer 4

Billions of stars are in this very galaxy and with billions of galaxies in this universe there are more stars than grains of sand on Earth.

Answer 5

think about it probably only half of 1% of the universe is probably charted we will never know unless we step are technology game up

Answer 6

trillions and trillions

Answer 7

Somewhere between 200-400 billion in our galaxy.  There are hundreds of billions of galaxies.  You can do the math.

Answer 8

"sun" refers to Sol, our star so technically there is only one. ^^

Answer 9

I can put it at (2^263 -1) no more no less. But who will be the judge?

Answer 10

If, by suns, you means stars,

In our Galaxy: around 250 milliard  (a thousand million; called a billion in the short scale).  This is the number I found when I wrote an essay on this in 2006.

Some estimate up to 400 billion (and that number could make sense).

In the visible universe (the portion of the universe we can see):

70,000 million million, million as estimated by astronomers in 2003.

A 7, followed by 22 zeros.

In the long scale, that number is called 70 trilliard.

In the short scale (used in most English speaking countries) the number is called 70 sextillion.

Of course, God can count a lot higher:  if the universe really is infinite in size and if it is more of less the same everywhere (on a grand scale), then the number of star in not finite -- it is infinite.  (But we do not know if the universe is infinite)

Answer 11

Actual number unknown.

There are 200 billion stars in our galaxy, and there about 100 billion galaxies in the observable universe.  If they are the same size on average as our own, that is a lot of stars.

But there could be an infinite number of galaxies in the entire universe, we don't know.

Answer 12

There are more sun/stars in the Universe than there are grains of sand on all the beaches of the world.

Answer 13

ask God if he can count that high

Answer 14

a lot
