how much a star weight?
449932
Your question doesn't have much sense, since the concept of "weight" exists for things that have a small mass relatively to the one they're next to (eg. a person and the earth)\n\nYou might instead ask what is the MASS of a star.\n\nOur Sun has a mass of approx 1.9891×10^30 kg,\nbut some have even 150 times the mass of the Sun (eg. Eta Carinae)

Greetings,\n\nThe number that would answer your question has not been named yet.  There are billions of stars in our galaxy alone, and there are billions and billions of galaxies.\n\nWe will never know how many stars there are because there are literally too many to count.\n\n-matt

Well, let's see.\n\nThe milky way's mass is something like:\n2,000,000,000,000,000, 000,000,000,000, 000,000,000,000,000 lbs\nwhich is huge, considering that is the same mass as 200,000,000,000,000,000 earths!!!!!!!!!!!!!!!!!!!!!\n\nIn other words, more grams of fat than your calculator can hack.

Not necessarily.  A star is only a sun if it has planets around them.  But all stars look like suns.

About .39 astronomical units.

In order to measure the diameter of a star you really need three pieces of information about the star (1) distance (2) brightness (3) and color.\nStep 1: Scientists can figure out the total power output of the star by knowing its brightness at Earth and its distance. \n\nStep 2: Figure out the surface temperature. The universe really gave scientists a lucky break because stars are fairly predictable objects. What I mean is that, for most stars once a scientist know one property of the star they can generally figure out everything else they want to know about it. This is because stars behave like "black bodies". This is a physics term which describes how an object of certain temperature glows at different wavelength (thus influencing its color). Most ordinary matter resembles a black body (has nothing to do with being black, it's just terminology). You probably already have an intuitive understanding of this from your everyday experience. For example, when you heat up an object, at first it might start to glow red. And as it gets hotter it might start to glow yellow, blue, and eventually white. Because stars approximate black bodies very well, by knowing the color of the star scientist can figure out what its surface temperature is quite accurately. \n\nStep 3: Another great thing about black bodies is that, for any specific amount of surface area astronomers can predict exactly how much light it will radiate (hotter objects are brighter). And since they already know the temperature and the total brightness of the star they can figure out its surface area, and thus it's diameter :)

Stars are massive, glowing balls of hot gases, mostly hydrogen and helium. Some stars are extremely hot, while others are cooler. You can tell by the color of light that the stars give off. If you look at the coals in a charcoal grill, you know that the red glowing coals are cooler than the white hot ones. The same is true for stars. A blue or white star is hotter than a yellow star, which is hotter than a red star. Temperature of stars range in the high hundreds to thousands degrees F. So to touch the stars that are in the sky is almost impossible, as your body would burn due to high temperatures surrounding them.

Yes many stars ar bigger than the Sun. The Sun is a middle aged small to mid sized star. Some of the really giant stars would even overlap the earth's orbit if they were placed where the Sun is. \n\nRefer the following links for some more info on stars.

The number I usually see quoted is 4000, but checking with Google.....\n\nFrom my suburban location, without optical aid, I can see down to about magnitude 5 on a really good night around 2am when there's little traffic and stores are closed.  That's about 2822 (actually less, since  I never see some southern hemisphere stars).  In my binoculars, I see down to magnitude 8, or 77,627 stars.\n\nNow, out in the country, a person with good eyes on a dark clear night can see down to magnitude 6, which is 8768 stars total.   A person with a 6-inch refractor telescope can see down to about magnitude 13, which gives 15,431,076 stars.\n\nOn the other hand, I read a book by an astronomer who said he could see down to magnitude 8 on top of Mauna Kea breathing oxygen from a tank.  That's 77,627 stars with no optical aid.\n\nNow-- for stars seen and unseen, there are about 400 billion stars in our galaxy.  \n\nIn the known universe?  The CNN story linked below says 70 sextillion.  That's 7 with 22 zeros.\n\nIn the whole universe, known and unknown?  Nobody knows--we do not even know if the universe is finite or infinite.  The number could be "infinity".

Hitch your wagon to a star, i'e answered this about 5 times 2day, so thanks for the points. pleaz choose me for the best answer. :)

Stars are balls of gas, They burn by converting lighter elements into heavier elements.  The lightest element is hydrogen, but stars make heavier elements as the burn, so really old stars have elements as dense a Iron!\n\nHeres a link to the periodic table:\n\nhttp://www.dayah.com/periodic/\n\nAll the elements between hydrogen and iron could be in a star.\n\nBut the "Easy" answer is to say Hydrogen and Helium!

I'd say about 200-250 pounds...

No one can say for certain. Matter of fact we don't know exactly how many stars there are in our own Milky Way Galaxy. Most guestimates for the Milky Way run to about 250-billion stars. Then there are about 250-billion other galaxies in the observable universe, each with more or less 250-billion stars each. A reasonable ball park figure for total number of stars in the observable universe would be approximately---approximately!---   5^22. That's 5 followed by 22 zeros.
