Quizplus · Accepted Answer

The typical main sequence lifetime of a G-type star is around 10 billion years. This is because G-type stars have a lower mass than more massive O, B, and A-type stars, which have shorter lifetimes, and are more massive than smaller and cooler K and M-type stars, which have longer lifetimes. The typical main sequence lifetime of a G-type star, like our Sun, is about 10 billion years.
