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)

Consider a photon produced in the center of the sun. (A) How long this Would it take photon to cross the sun and reach the surface if there was no absorption? (B) Suppose the photon is continually absorbed and reissued so that its path to surface can be considered as a random walk process. Assuming that reissues occur instantaneously after each absorption, estimate the time needed for the photon to reach the surface.

Use the inverse square law to estimate how the brightness of the Sun would change if you moved from Earth at 1 AU to Saturn's location at 10 AU (i.e., give a fraction or percentage, not magnitude). Then, the brightest known star is R136a1 with an absolute magnitude of -12.5, explain why you cannot make a precise determination of its brightness as seen from Earth without more information
