My friend told me that the sun is going to get smaller and smaller every year because it's getting used up? I've read that the power output is 4 x 10^26 Watts. How can i figure out how much mass it's losing a second? because then I will be able to find how long the sun will be able to shine on me and my children (hopefully).(adsbygoogle = window.adsbygoogle || []).push({});

thanks.

I don't really know how to attempt this problem because it's really random and i don't know any formulas for power.

merci.
