Vega is one of the hottest and brightest stars in the universe. Vega has a blue/white glow, which makes him look 10x bigger than the sun. Vega is also famous and popular in this universe. Also the brightest out of it's class . And the fifth brightest star in the sky. Vega is also called the "harp star" for its brilliance and amazing blue-white color.
Vega just like any other star, was born in a nebula. In December 1989, Vega's mother gave birth to the best star ever


protostar& nebula
Name of star: Vega
Color (race): Blue-white
Surface temperature: 11,300 kelvin
absolute magnitude: 65 (brightest star in its class (lyra)
luminosity: 50
type/class: aOVa
average radius: 2.5
elements- helium, hydrogen
Vega's current stage is the main sequence. Where he is starting to grow older into a teen/ young adult. He's starting to grow strong, brilliant and project more of amazing blue-white color. (forming helium deep in interiors)
The process of hydrogen fusion begins taking place in it's core . Fusion produces enough radiation pressure to counteract the force of gravity; there for gravitational collapse ceases. The protostar has become an actual star in its main sequence phase.
main sequence




Red giant
this is the stage in Vega's life where it would be considered middle-aged. When Vega's core runs out of hydrogen, gravity has its way once more-- that is, until temperatures rise high enough to allow helium fusion, which produces the outward pressure needed to stabilize things. When no helium is left, the cycle begins again. Vega is starting to get gray hair, and some wrinkles. He also starts to get weaker, Vega is trying to maintain equilibrium. It's headed to being a white dwarf.

the inward force of the star is pushing out lots of energy helping the star maintain its equilibrium. The outward force of the star is gravity pushing on to help it maintain its shape
