Name the largest star in the universe?

Answer 1

Roseanne Barr?


edit:All these scientific answers....blargh. I STILL say the biggest star is Roseanne. I mean, come the hell on, anyone seen her? Then again.....how can you miss her >.>

Answer 2

In order to know what the largest star in the universe is we would have had to look at all the stars. We haven't come close to that - we haven't even looked at all the stars in our galaxy. There are about 100 billion stars in our galaxy, and about as many galaxies in the observable universe so you might understand why.


The best I can do is tell you what the largest known star is, but to do that I also need to know what you mean by largest. Do we pick the brightest, or the largest in volume, or the most massive (the one with the most mass)? More massive stars are generally less dense so take up a proportionally bigger volume. The most massive known is generally accepted to be the Pistol Star, which has a mass about 100-150 times that of the Sun,and is about 10 million times brighter.About 100 Suns would provide the same amount of stuff as the star, but we would need more that 100 Suns worth of volume to fill in the space it takes up.

Answer 3

VV Cephei is an eclipsing binary star system located in the constellation Cepheus. It contains a red supergiant. If it replaced the Sun in our solar system, it would extend to the orbit of Saturn. It is 315,000 times as luminous as the Sun.

Guess that answers your question.....

Excuse me, but VV Cephei is " 1 9 0 0 " times larger then the Sun. The Pistol Star is merely 340 times... It's famous cause it's the most luminous in the Milky Way galaxy (about 10 million times brighter than the Sun). Within 3 million years it will be a Supernova anyway !

Answer 4

Do you mean largest radius or largest mass? There's a HUGE difference (no pun intended :-)

The Pistol star has just about the largest mass as any star we've seen (of course there are many we haven't seen). A red supergiant star would have the largest radius, perhaps one of the red supergiants mentioned above is the largest we've seen so far.

Answer 5

The sun is the largest star in the universe. Apart from the Sun, the star with the largest apparent size is R Doradus

Answer 6

The largest star in the universe has not been discovered yet for the universe is big, very big, so big you can not imagine

Answer 7

Betelgeuse is one of the largest we have studied .. I have no doubt that there are far larger ones out there, however.

As a note ... the person who said the sun is very misinformed .. our sun is actually a rather small and very average star.

Answer 8

Very interesting how many people named the sun as a large/largest star. I appreciated the thoughtful answers from others.

Answer 9

There are 3 current record holders known to man and they are the same size.
KW Sagitarii (distance 9,800 light-years), V354 Cephei (distance 9,000 light-years), and KY Cygni (distance 5,200 light-years), all with radii about 1500 times that of the Sun, or about 7 astronomical units (AU).
Damn, cut and paste makes me a genius!

Answer 10

So many people are saying "the sun...no duh" ... well ... for your information the sun is the biggest in our Solar System, not the universe. I dont think anybody has any idea how big the universe is... you cannot compare it to anything (literally, nothing could be bigger). It is impossible to know. We do not fully know what is out there.

So the answer to your question is unknown till today.

Answer 11

sorry frnd can answer that
coz there r mo stars in the universe which v have not even discoverd
so v cant tell
