* Larger mass stars: Live shorter lives. They burn through their fuel much faster due to higher core temperatures and pressures.
* A star 10 times the mass of our Sun might only live for a few million years.
* Smaller mass stars: Live much longer lives. They burn their fuel slowly and efficiently.
* A star half the mass of our Sun could live for trillions of years.
Our Sun: Our Sun is a mid-sized star with an expected lifespan of about 10 billion years. It's roughly halfway through its main sequence stage.
Key takeaway: The more massive a star is, the shorter its life on the main sequence.
