Most of the particularly bright stars have several names; a Chinese name, and Indian name, a polynesian name, and so on. In the Middle East, the Egyptians and Babylonians had their own names, which were interpreted or modified by first the Greeks, then the Romans. The first document that we might call a star catalog was compiled by Claudius Ptolemy, a Greek who lived and worked in Alexandria, Egypt. This book survived the collapse of the Roman Empire, and was translated into Arabic, when it got the name we still use, the "Almagest".
A great number of Greek and Roman books that did not survive the fall of Rome were preserved in the Library of Alexandria in Egypt, and many of these were recopied and carried to other parts of the Persian empire. In the 1300s and 1400s, when the Spanish conquered the Arabic province of Andalusia (which we know as "southern Spain") Spanish and Christian scholars were able to obtain, and retranslate into Latin, much of what we now think of as "Roman" and Greek documents. The Almagest, Ptolemy's star catalog, was among them.
So if you're thinking about a bright or distinctive star, the name probably came from the Greek or Phoenician language, translated into Arabic, and translated back into Latin. In many cases, the name we use today is the Arabic name.
Small or dim stars are generally referred to by a catalog number, or by a Greek letter prefix and the name of the constellation in which it appears. So, "Alpha Orionis" is the brightest star in the constellation Orion. Since it is a bright and distinctive star, it has its own name; "Betelgeuse".
Its around 2.26 solar radii from pole to pole (where one solar radii is our suns radius) and around 2.78 solar radii across the equator - so its a flattened, squashed sphere or oblate spheroid shape. Vega is a rapidly rotating star. It only takes only 12.5 hours to rotate once, meaning that the star bulges out more at the equator.
All stars are made primarily of hydrogen, with lesser amounts of helium and trace amounts of heavier elements. The precise composition of each star is a little different, depending on the mass and age of the star.
The star Vega was renamed in the International Star Registry in 2003. The name is now "Ayline Anderson Dearie Duquette".
Vega is the brightest star in the constellation Lyra.
Lyra. It's the brightest star in this constellation and one of the brightest in the night sky over all.
Spica (α Vir, α Virginis, Alpha Virginis) is the brightest star in the constellation Virgo.
It has an absolute magnitude of -3.55
Most stars contain large amounts of hydrogen, less helium, and small amounts of heavier elements.
Vega (Alpha Lyrae) is a blue-tinted white main sequence star in the constellation Lyra.
It has a spectral class of A0V
Vega's apparent magnitude is +0.03.
Vega's apparent magnitude is +0.03.
Vega's apparent magnitude is +0.03.
Vega's apparent magnitude is +0.03.
Spica has a surface temperature of 22,400K and an absolute magnitude of -3.55Rigel has a surface temperature of 11,000K and an absolute magnitude of -6.7So the question is incorrect.
The absolute magnitude of Porrima is 3.04.
-3.64 is the absolute magnitude of Polaris.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
VY Canis Majoris has an absolute magnitude of -9.4.
Spica's absolute magnitude (Mv) is: −3.55 (−3.5/−1.5)
Spica has a surface temperature of 22,400K and an absolute magnitude of -3.55Rigel has a surface temperature of 11,000K and an absolute magnitude of -6.7So the question is incorrect.

You cannot ask for an absolute magnitude and specify the distance, as the absolute magnitude is derived from a set distance of 32.616 light years.At that distance, the absolute magnitude of the Sun is +4.83From Earth the apparent magnitude -26.74
-3.64 is the absolute magnitude of Polaris.
No. Apparent Magnitude is what it looks to be, whereas absolute is its actual mangnitude.
