about how big is a star.? could you compare it to the size of something else,please?

Answer 1

check out this site. It's pretty cool. It shows relative sizes of planets, stars, suns, huge stars, average stars, etc.

Answer 2

Stars are very large (much larger than the planets), so there isn't anything on Earth we could compare with our sun (which is a relatively average-sized star). But let's try this.

A star is measured by its mass - the amount of matter in the star. Mass controls how bright it is, how hot it is, and how big it is (sort of).

Now.
It would take the 318 Earths to equal 1 Jupiter mass.
A star that's just barely massive enough to ignite fusion to shine as a star would need to have at least 75 Jupiter masses.
Our sun is actually 1047 times the mass of Jupiter, or about 332,946 times the mass of the Earth.

Another way - the sun has the same mass as about 27 million Moons.

Answer 3

Chandrasekhar limit
Chandrasekhar's most famous success was the astrophysical Chandrasekhar limit. The limit describes the maximum mass (~1.44 solar masses) of a white dwarf star, or equivalently, the minimum mass for which a star will ultimately collapse into a neutron star or black hole (following a supernova). The limit was first calculated by Chandrasekhar while on a ship from India to Cambridge, England, where he was to study under the eminent astrophysicist, Sir Ralph Howard Fowler. When Chandrasekhar first proposed his ideas, he was opposed by the British physicist Arthur Eddington, and this may have played a part in his decision to move to the University of Chicago in the United States.

Answer 4

well think of it this way. Our Sun IS a star. It is classified as a medium star. So there are stars out there that are alot larger than our sun. Also there are ones smaller. Since the earth is like 1/100 the width of the sun, its realy hard to actuly try and immagine what its like scale wise. I actuly dont this its comprehendable

Answer 5

Our Sun is a typical star. It is a little over 100 times the diameter of the Earth, and you could fit 1 million Earths inside its volume.

This is a good graphical comparison of the planets in our solar system, our Sun, and some other stars:

Answer 6

if you picture the sun as about the size of an apple, the earth is about the size of a pin. when you get to truely massive stars and picture them about the size of an apple, earth would only be visible with a very powerful microscope.

Answer 7

If you suppose that the earth is in the center of a simple star (such as sun) than the moon will be in the middle of the star radious.

Answer 8

The sun is considered a somewhat smaller-than-average star. Yet it is about 870,000 miles in diameter, which is about 1000x longer than the earth diameter. Some of the largest stars (the red giants) are about 300 times the diameter of the sun.

Answer 9

Our sun is an average star. The sun contains 99.9% of all the matter in our solar system.
