what is the scientific name of the biggest and brightest star?

Largest Star (By Size) - VV Cephei - 1900 times diameter of sun\n\nMost Luminous Star - LBV 1806-20 - 40,000,000 times luminous than the sun\n\nHowever, the brightest objects in our universe are the quasars... Check the links below for more info\n\nI hope these were the answers u were lookin for...

The total number of known stars is 10,000,000,000,000,000,000,000, when we write this number out. This figure would be pronounced as "ten billion trillion" stars.\n\nAs technology improves, this number will continue to increase since there are many more stars out there.

If you mean visible to the unaided eye and defining the dippers, seven each.  In the Little Dipper you have Polaris and Kochab, the others are not particularly bright and have no names, just catalog numbers.\nIn the Big Dipper, one could argue that there are eight visible stars, as the middle star in the handle, Mizar, has another star, Alcor, right next to it.  The two stars at the end of the bowl of the Big Dipper, Merak and Dubhe, point straight to Polaris.

I assume you mean "star" and not "sun", as in OUR sun, in the first question.  In that case, a supernova is essentially the spectacular explosion that occurs when a star of a significant sized mass ends its life.  IN that case, all the elements with a periodic table number higher than oxygen are created.  In addition, the remaining core of the dead star becomes so dense, that it creates an object that even light can't escape.  This object is now a black hole.\n\nOur sun is not big enough to supernova, therefore it will just die out and become a black dwarf when it is dead.\n\nDefinition from the Big Wiki...\n\nhttp://en.wikipedia.org/wiki/Supernova

"The star, known as LBV 1806-20, tips the scales of stellar masses at about 150 times the heft of the Sun. It shines up to 40 million times brighter than the Sun. The previous title-holder called the Pistol Star, is a mere six million times brighter than the Sun and weighs about 100 solar masses."

The brightest stars still carry the names they were given to them by (mainly) Arabic astronomers (Aldeberan, Altair, etc).    Many of the other brighter stars are given greek or number representations within the constellation.  Alpha-Centari is the brightest (alpha = 1st letter) in the constellation centarus.  This goes all the way out through numbers like the famous star 51-Peg (the 51st brightest star in Pegasus).\n\nThese days most stars just carry a catologue number, or a particular set of coordinates on the sky, so that anyone can find the star you are talking about.  No star has been given a proper "name" in many centuries.

Blue giant stars have left the main-sequence after exhausting their hydrogen fuel, leaving behind helium. Thus, blue giants fuse helium as their energy source. The star Rigel is a classic example of a blue giant.\n\nThis website for comfirmation --> http://www.enchantedlearning.com/subjects/astronomy/stars/startypes.shtml\n\nGod is spelled B-I-G B-A-N-G\n\nPBrax@netscape.com

Star's are for the most part the same as our star/sun. The difference being we named our star The Sun.

It's name is Polaris and is the brightest star in the Ursa Minor constellation. This can help you more: \nhttp://en.wikipedia.org/wiki/Polaris

There are only 2 that are bright enough to see with the naked eye, that is, they have a magnitude less than 3. Alphard is the brightest star of the constellation, with an apparent magnitude of 1.98. R Hydrae is intermittently visible because it has a varying magnitude between 3.5 and 10.9.

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 :)

Venus is the morning star as it is seen at dawn in the east . It is a planet and not a star. Being closer to The Sun than our Earth, it reflects the Sun light and appears very bright. \nDuring some part of the year it appears near the western horizon at dusk and then it is known as the Evening Star.

We don't yet have the technology to answer this question.\n\nEDIT: To dogoutburner: That's the largest in our galaxy. We have no idea the largest in the universe.

The Sun moves quite fast around the center of our Galaxy, at a speed of about 800,000 kilometers per hour (500,000 miles per hour).  Even still, it takes the Sun about 250 million years to complete one orbit!\n\nA few years ago, the most massive star was the Pistol star.  It's about 100 times more massive than the Sun is.  In fact, any star that massive won't be stable.  The Pistol star got its name because it is the source of the Pistol nebula - the Pistol star is unstable and is constantly blowing off material, material we see as the Pistol nebula.\n\nWhen a star begins to "die" it expands into a red giant or red supergiant.  The largest (in size) supergiants can be larger than the size of Jupiter's orbit.  Such a star won't last too long (only a few million years, if that) before it explodes as a supernova.

M31, the Andromeda Galaxy, is the most distant object easily seen with the naked eye. In a very dark sky, you may be able to see M33, which may be 3 million light years distant.\n\nIt's a little more difficult to determine what is the  most distant individual star that can be seen with the naked eye, as it is apt to be some faint, nondescript star. Also, it is difficult to accurately determine the distance to a single star at distances over 1500 light years. P Cygni, a fifth magnitude star in the constellation Cygnus (the Swan or Northern Cross) is a very luminous star possibly 6000 light years away. This is probably a reasonable approximation of how far away a star can be seen. Note that this is still in our Milky Way Galaxy, which is around 100,000 light years in diameter. However, you might be able to see a supernova in a nearby galaxy.  SN1987A in the large Magellanic Cloud reached third magnitude, and it was fairly dim for a supernova.  (About magnitudes: six is about the dimmest visible, smaller numbers are brighter. The brightest star, Sirius is -1.)

The place which advertises the most is the International Star Registry (linked below), but frankly you are better off spending your money on something else. The "name" that you give the star will not have any real legal or scientific meaning, so essentially you are paying a lot of money for just a slip of paper. \n\nNote this disclaimer from the small print on their site: "International Star Registry star naming is not recognized by the scientific community. \nYour star’s name is reserved in International Star Registry records only." In other words, they publish a book with the names that their customers have paid for, but frankly anyone could publish a book with any list of names in it. It has no real meaning.\n\nNaming stars is basically a scam.
