Is it true that i'm hotter than a piece of the sun the same weight?

Question

I was watching the BBC's programme 'Atom' when i heard the presenter explaining that a human is hotter than a piece of the sun the same weight. Did i hear right and could someone explain why?

Answer 1

Energy absorbed at earth distance from sun=1300J/s/m^2
Integrated flux of solar power=4*pi*R^2*1300 where R=1.5x10^11m (earth-sun dist) and 4*pi*R^2=Area of the total sphere enclosing that flux (Gauss's Law)
So total Solar Flux =3.6x10^26W
Human power output at temp =310K, surroundings 273K=100W
Power output per unit mass for sun=
P/M=3.6x10^26/2x10^30= 1.8x10^-4W/Kg
Power output/Kg for human (ave)=
p/m= 100/60= 1.67W/kg.
So human power output/kg is equivalent to being about 10,000 times hotter than a 'sun' of your own mass. An effective themonuclear power source to fit on planet earth will have to be millions of times hotter than the sun- or you would have to build it in space!

Answer 2

You produce more energy per second than an equivalent piece of the sun, but you are colder. Why? Because the heat you produce escapes from you, whereas in most of the sun there are thousands of miles of sun around you. Over time this means the heat escapes only very slowly indeed, and your temperature rises to a very great heat as the heat cannot escape.

Counterintuitive, but true.

Answer 3

i believe the correct way of saying this is that the average human body surface emanates more heat than the same amount of the surface of the sun.

Answer 4

Trouble here is language again. You see "hot" has more than one meaning.When you say "hotter" do you mean with a higher temperature or do you mean sexier?

Answer 5

that depend where you are talkin about on the sun
the surface ,,photosphere,,,core.
I somehow doubt if you are as hot as the core at 50 million plus k..
now my horse says this not me..

Answer 6

its not true. dont beleive anything on bbc
