How many stars are there in the universe?
Based on current estimates, there are between 200 - 400 billion stars in our galaxy (The Milky Way). There are possibly 100 billion galaxies in the Universe. So taking the ave…rage of our galaxy, gives approximately 3 x 10 24 stars. So about 3 septillion. This has been equated to the same number of grains of sand that are on Earth. One source (BBC) stated that there are about 1,000 stars to every grain of sand on Earth!! There are an estimated 100 to 200 billion galaxies. So taking a conservative number of 100 billion stars per galaxy gives an approximate total of 10,000,000,000,000,000,000,000 stars. (Which is 10 sextillion) The newest estimates gained by the Hubble space telescope places the estimate of 500 billion Galaxies each with about 300 billion stars for each galaxy.
The most recent estimates place the number of stars in the observable universe at around 10 23. That's a 1 with twenty-three zeros after it. More precisely, that would be 100… sextillion. "The universe is so big, it doesn't even make sense to talk about how big it is."
In the observable universe there are about 80 to 100 billion galaxies with varying numbers of stars in each. A rough mean average for the number of stars per galaxy is 400 bil…lion. It is thought that there are from 30 to 70 billion trillion (i.e. 30 to 70 sextillion) stars in the observable universe. Whilst the estimates differ somewhat, the number of stars seems to be in the sextillions, which is a 1 followed by 21 zeros. There are many reasons why our estimates vary as much as they do. An important point to consider is that when we observe distant objects such as stars, we don't see them as they are now, but as they were in the past. The reason we see into the past as we look out into the universe is because the light we see takes a finite amount of time to reach us. As such, some of the stars we see, particularly those in very distant regions of space (relative to earth), may no longer be counted as stars. Conversely, new stars in distant regions may have already formed but we wouldn't see them until light from those stars reaches us here on earth.
Nobody can really tell. There are an estimated 100,000,000,000,000,000,000 (100 quintrillion) probably more. Of those it's estimated to be about 3,000,000,000,000,000 (3 th…ousand trillion) will be hypergiants.
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.
4 i think in the movies. In the expanded universe there are many more.
In general terms, with people of normal vision, there are intotal around 8,000 stars observable with the naked eye.This breaks down to 4,000 in the north, and 4,000 in the… south,non-overlapping. But in the north, for example, half the stars inyour year-round sky are obscured by the sun; so roughly 2,000 starsare visible, on average, in the nighttime sky on any night. Andthis assumes very good viewing conditions. This may not sound likea very high number, but we have become used to hearing astronomicalthings described with correspondingly huge numbers. Try coming upwith a method of estimating the number of stars you actually see;you probably won't be too far off from 2,000 if you do itcarefully. We are talking about stars in the Milky Way; a smallnumber of galaxies and clusters can be seen as 'stars' with thenaked eye, but no stars outside of the Milky Way are observable..
The Universe is a term used to explain the size of everything there is no way to know how big or of what content it is.
Answer 1: Hundreds of billions of billions. Updated: As of 2009, it was estimated to be around 10 23 stars in the observable universe. However, it was recently disco…vered that we may have been missing most stars of the red dwarf variety and now it is beginning to look like the 10 23 figure would now have to be tripled. So its about.... 3,000,000,000,000,000,000,000,000

What a great question! The Milky Way galaxy, of which the Sun is a part, has approximately one hundred billion stars. Keep in mind that stars and being created and destroyed a…ll the time. As to how many galaxies there are, and a rough estimate of how many stars, it is hard to say because not all of the universe, such as it is, has been observed, and hypotheses vary wildly, so any guess is probably not helpful.
Carl Sagan used to say, "there are 100 billion galaxies each with 100 billion suns." 100 billion x 100 billion = 10 22 Although today, many scientists estimate that numb…er to be even larger still. There is no way of knowing as our understanding of the universe is still very small. It's like asking how many grains of sand there are on the Earth surface, it would be impossible to give an exact number. Funny enough, some say that the number of stars actually exceeds the number of grains of sand!
Literally because it is so big. It is impossible for a human mind to imagine how big it is. There is so little out there relative to to the distance between each object. The n…earest star to us is 4.2 light years away and the furthest you can see with the naked eye is around 4000 light years away so that should give you an idea of just how large space is. And again to emphasize, that's just with the naked eye.
That depends on the size of the Universe. It is not currently knownhow large the Universe is; or even whether it is finite or infinitein size. The OBSERVABLE UNIVERSE has roug…hly 1011 galaxies, and agalaxy typically has 1011 stars; for a total of about 1022 stars.If you write it out, that's a 1, followed by 22 zeros. cw: It was once argued that there couldn't be an infinite number ofstars because the sky would be a blanket of white. That argumentwas before space dust, gravity, etc. were known to affect thetransmission of light in the Cosmos. The key word, of course, asDr. Zonneveld has said, is Observable.
