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.
The Sun is expected to exist as a main sequence star for some 10 billion years, but a red dwarf one tenth its size ought to shine on for a thousand times longer, ten trillion years. In our galaxy, the Milky Way, red dwarfs are the most common type of star. In the vicinity of the Sun, 80% of the stars are red dwarfs.n the Northern Hemisphere, look towards Leo, home of Wolf 359, a red dwarf a tenth the mass of the Sun, and only 7.8 light years away. Observers in the Southern Hemisphere can look to Alpha Centauri, actually a multi-star system one of which is celebrated red dwarf Proxima Centauri.
