Suppose that there is a planet in the solar system with a semi-major axis of a, of 77.2 A.U.that is an icy?
object with an albedo A, of 0.50. What is its surface temperature assuming that its only source of heat is sunlight, and that the planet radiates as a black body. Suppose that th eplanet has the mass and radius of pluto. WOuld such a planet be expected to retain carbod Dioxide ( mass=44xmass of hydrogen)?
This is what i got:
(1-A)*lsun/sigma*16*pi*d^2= 1-0.50*3.9*10^26/5.67*10^-8*16...
= 1.95*10^26/1.507*10^7= 1.293*10^19= 59966.2K
I see this is to hot cause its a icy planet but still lost help ma plz

Stop for a minute... Look over your question. Note 2 things
a. 77.2 AU
b. An icy object
Now start over slowly and find your mistake...YOU CAN DO THIS!!!
