Sun O1 (Bright Blue) (celestial objects Sun)

A hot, luminous and blue stellar body belonging to a relatively rare class of main-sequence stars. Often large and massive, these stars very quickly burn through their core hydrogen fuel supply and therefore have short lifetimes on the main sequence. These stars emit a tremendous amount of ultraviolet radiation and the largest among them will typically go nova after only a few million years. Smaller stars of this type can cool sufficiently that they will turn into rapidly-rotating stars dominated by carbon-nitrogen-oxygen (CNO) cycle nuclear fusion.
