Astronomy can be very intense and mind melting as well. Like the fact that Saturn's huge moon Titan has a thick atmosphere that is waiting to be made into small earth!
How awesome is that? 
Ugh, please don't make me do the math on this -- I've just recently been doing planetary science problems like this and -- goddammit I'm going to do the math. D:
Solar flux at 1AU is S
E = 1.37x10
6 erg*s
-1*cm
-2.
Saturn, and Titan with it, have an average heliocentric orbital distance of roughly 9.5AU. So by inverse square law, the solar flux for Titan is S
E/9.5
2 = 1.85x10
4. Call that value S
T, for solar flux at Titan.
Equilibrium temperature for a spherical blackbody (ε=1) with bond albedo A
B (Earth's Bond Albedo is ~0.31, let's say if we made Titan earthlike it would be the same), is given by
T
e = [(1-A
B)S
T / 4εσ ]
1/4Plug in the values, we get an equilibrium temperature of 87 Kelvin. (That's -303°F)!
(Compare that with the actual surface temperature, according to wikipedia, of 93.7K -- not a bad calculation!)So yeah, good luck making Titan earthlike.
