Yes.

Me neither.  Just a student for now.

_In_ the Sun; to be precise, only in the *core* of the Sun.

Correct.  And perhaps more importantly, infrared radiation to allow for 
liquid water here, and UV radiation to allow for photosynthesis (if one 
follows the definition that “light” is only [human-]*visible* light).

Not much.  Google is your friend. [psf 6.1]

BTW, unless one wants to emphasize a larger mass in relation to a smaller 
mass, one uses “m” as the symbol for mass in physics, not “M”.

Yes.

Correct.  And that is not going to happen.  The end of the Sun (as we know 
it) and of all the inner planets, including Earth, will come in a far more 
spectacular way in any case (in about 2 to 5 billion years, short scale).

And now I should click through all folders to find your *wrong* calculation?

I really have better things to do.
