Re: [Space] How much does a Gas Giant heat it's moons?
They also occasionally block sunlight from the other, so it's likely a wash, and in any case most of the time the effect is negligible.

Cool, thanks. I was afraid my double planet system had even one more hassle than those I already knew about.

Re: [Space] How much does a Gas Giant heat it's moons?
So if I've got a moon of .56 Earth diameters (.23 radius) orbiting 61.07 Earth diameters from a Gas Giant the Blackbody temperature of the moon is increased by 4% of the Gas Giant's temperature? Is that correct? And how do I calculate the temperature of the gas giant?

Re: [Space] How much does a Gas Giant heat it's moons?
No, for several reasons. First, we need the radius of the gas giant. Second, you actually add T^4 from all sources and then take the 4th root, so if the secondary heat gave a temperature of 4% of the primary, the actual increase is (1 + .04 ^ 4)^1/4 - 1, or 0.000064%

For a moon around a gas giant, however, it is more likely. You'd have to figure out the axial tilt of the gas giant and then the semi-major axis and
