At this rate how long will the sun last?
To estimate the age based on this you need to know:
Percent of sun currently hydrogen – the sun is about 73% hydrogen by mass
6.5 x 1014 J/kg is released converting hydrogen to helium
(You looked up the mass of the sun in kilogram You looked up the power of the sun in Watts (Joules/second) Using these four factors you can come up with the expected life of the sun)
