Detailed explanation-1: -A star’s life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star’s mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born.
Detailed explanation-2: -The more mass a star has, the faster it will convert its hydrogen fuel into helium. It turns out that high mass stars, even though they have more fuel, use up that fuel much more quickly than low mass stars can. So, low mass stars have much longer lives than high mass stars!
Detailed explanation-3: -A smaller star has less fuel, but its rate of fusion is not as fast. Therefore, smaller stars live longer than larger stars because their rate of fuel consumption is not as rapid.
