:::::''"the entire idea that the sun could provide sufficient energy to increase their average temperature is not based in reality"'' I am disagreeing but I don't know what I am disagreeing about. Sunlight on Pluto is insufficient for solar temperature fluctuations? --[[User:Jpatt|jpatt]] 00:51, 27 February 2009 (EST)

:::::Consider the distances involved: Pluto is so far away that the sun would at best appear as a very bright star if you stood on the surface and tried to find it. Granted, Pluto isn't so far away that it receives no solar energy whatsoever, but the amount (inverse square law) is so negligible that you can't ascribe significant weight to it. In fact, Pluto only warms to the point of having a minimal atmosphere after it's orbit changes by almost 3 billion miles.
:::::I don't want to run into 90/10 problems, but again I gotta ask: how can we compare Pluto to the Earth, or even Mars to the Earth when they are so different that they are barely similar?[[User:Jirby|Jirby]] 01:05, 27 February 2009 (EST)
