Main Sequence Stars section of astrophysics option for NSW HSC Physics course. ... 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 (10MSun) star will only last 20 million years (2.0× 107 years) on the main sequence.
