I guess we assume the temp is uniform over the surface as is the incoming power (obviously untrue)
5.67*10^-8 T^4 = 1700
T^4 = 300 * 10^8
T = 4.16 * 10^2 = 416 K
416 - 273 = 143 C
Hotter than boiling water. Habitable?
You recently read that a new possibly habitable planet was discovered. The planet, Burt, receives 1700 W/m2 from it’s companion star. If planet Burt has a a radius of 6500 km and acts like a blackbody ( emissivity =1 ) and thus radiates same amount of energy it absorbs, what is its average suraface temperature. For comparison the earth has a surface temperaure of 278 K.
