What is the biggest star in the solar system except from the sun?

Answer 1

no one know what the biggest sun in the universe it grows every day making new stars it could be making one when you are reading this. a sun is a star but most of the time it is our star what only called sun. most of smart people say in our solar system there is just one star called to us the sun but we can see out of this solar system their say and we can see 7 more star and the biggest is a star unnamed and it is more then 1000.000.000.000X the sun it self and if you put earth next to it it is just a peace of dust of the size of them both and the biggest we can see is the 15 biggest star in the universe so that is the best I can get you I hope you like my answer

Answer 2

Apparent size

Our sun appears much, much larger and brighter than any other star because it is much, much closer than any other star.

Our moon is the second brightest object in the sky, and Venus is third.

To the human eye, all other stars appear to be the same angular size -- a single bright point.

The second brightest star (after the sun) visible from the Northern Hemisphere is Sirius, in the constellation Orion.

Some telescopes are powerful enough to resolve the disk of some of the closer stars. Pictures made by those telescopes show that R Doradus and Betelgeuse are the next-largest in angular size, both with an angular diameter of about 0.057 arcseconds.

Absolute size

Our Sun is not a very big star. Many distant stars are simultaneously much, much brighter (in absolute magnitude) and much, much larger (in absolute radius) and much, much heavier (in mass) than our sun.

Supergiant stars as VY Canis Majoris, VV Cephei, and Betelgeuse are well over 500 times the size (in absolute radius) of the sun.

Many stars such as LBV 1806-20, the Pistol Star, Eta Carinae, and Betelgeuse have well over 100,000 times the absolute luminosity of our sun.

Many stars such as the the Pistol Star, Eta Carinae, VY Canis Majoris, and Betelgeuse have well over 15 times the mass of our sun; but no known star has a mass more than about 120 times the mass of our sun.

Answer 3

One of the most luminous stars that is also relatively bright and well ḱnown that is visible to the naked eye is Deneb in the constellation "Cygnus" (the Swan) 60 000 times more luminous than our Sun an it has a mass of about 20 times the solar mass, it's diameter is probably more than 100 times that of our Sun.

Betelgeuse (in Orion) is a candidate for the largest (greatest diameter). With a diameter of over 1100 times that of our Sun.

Answer 4

The brightest star seen from Earth, aside from the Sun, is Sirius A. The Sun, of course, is nowhere near the largest star we can see. It only appears big to us because it is so much closer than any other star. Comment: That's not the answer to the question, of course. Even in big telescopes, all stars seem just like points of light from Earth. Perhaps the questioner meant the star we believe is the biggest, of those we can see.

Update: (Comment: This doesn't really answer the question, either.)

The top 10 brightest/biggest stars seen from Earth (minus the sun):

1 - Sirius (1.7 times the diameter of our sun, 9 light years away)

2 - Canopus (65 times solar diameter, 310 light years)

3 - Alpha Centauri

4 - Arcturus (26 times solar diameter, 37 light years)

5 - Vega (2.7 times solar diameter, 25 light years)

6 - Capella (12 times solar diameter, 43 light years away)

7 - Rigel (78 times solar diameter, 800 light years)

8 - Procyon (2 times solar radius, 11 light years)

9 - Achernar

10 - Betelgeuse (Alpha Orionis, 1180 times the diameter of our sun)

Comment. This is one possible answer to the question: VY Canis Majoris (2000 times solar diameter, 5000 light years away - not visible to naked eye). However estimates or the diameters of stars is difficult and there are other candidates for the "biggest star".

Answer 5

really someone asked this question??? the sun can't be seen at night with or without a telescope probably the cause of all that darkness wouldn't ya think

Answer 6

Proxima Centauri

Answer 7

Betelgeuse
