Vega is a bit over twice as massive as our sun. It is also much whiter, and much hotter and more luminous than our sun. It is only about one-tenth the sun's age (500,000 years) but like our sun, it is about at the midpoint of it's life right now.
The brightest star in the sky, is our Sun. It is a star. After the Sun, Sirius is the next brightest star, or the brightest in the night sky.
Rigel is approximately ten times LARGER than Sirius
Yes it is much bigger.Probably 5 suns can fit in sirius.Not only is sirius bigger but it is much hotter as well.
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
The brightest OBJECTS in the sky, after the Sun, are the Moon, followed by planets Venus, Jupiter, and Mars (on rare occasions, Mars is brighter then Jupiter), followed by the star Sirius.The brightest stars proper are Sirius, followed by Canopus, Toliman, Arcturus, Vega...
Vega represents the amount of light from a star.
Vega is the brightest star in the constellation Lyra.It has a spectral class of A0V meaning it's colour is white to blue-white.

ARE* the stars bigger than mars? To answer your question: Yes, much bigger. Since the Sun in our solar system is in itself a star and is much bigger than Mars, you can assume that all stars are bigger Mars. P.S. The Sun is considered a relatively small star compared to others in our Galaxy.
No, Vega is a main-sequence star, meaning it is currently fusing hydrogen into helium in its core. The star is relatively young compared to our Sun, so it still has a long life ahead of it on the main sequence.
The sun is a star, some stars are larger and other are smaller.

Vega is a star but zefinfino vega is not known as one.
Vega will be the north star in about 12,000 years time.
