Lifespans for main sequence stars have a vast range. Whilst our Sun will spend 10 billion years on the main sequence, a high-mass, ten solar-mass (10 M Sun) star will only last 20 million years (2.0Ã 10 7 years) on the main sequence.A star with a only half the mass of Sun can spend 80 billion years on the main sequence.tars are composed almost entirely of hydrogen and helium. A star such as our Sun is about 73% hydrogen by mass and 25% helium. If determined by number of nuclei then it is 92% hydrogen and 7.8% helium. The remaining 2% by mass or 0.2% by number is all the heavier elements.
This means that the core of the star is continuously mixed up, and the helium ash is carried away to prevent it from building up. Red dwarf stars use up all their hydrogen, not just the stuff in the core. Itâs believed that the smaller red dwarf stars will live for 10 trillion years or more. How long do stars last? The biggest stars last only millions, the medium-sized stars last billions, and the smallest stars can last trillions of years. We have written many articles about stars here on Universe Today. Hereâs an article about the biggest star in the Universe.
