The discussion centers around the energy radiated by Jupiter and the energy it receives from the Sun. Participants explore methods to estimate these values, including considerations of surface temperature, albedo, and the Stefan-Boltzmann law.
Participants express uncertainty regarding the precision of energy estimates for Jupiter, and there is no consensus on specific values or methods to obtain them. Multiple approaches and considerations are discussed without resolution.
Participants highlight limitations in precision due to factors such as temperature variations and the complexity of Jupiter's thermal balance, which may not be fully captured by simplified models.
Did you find its surface temperature and the Stefan-Boltzmann law? Jupiter is not a black body, but its (infrared) albedo should be listed somewhere as well.Ans said:I tried to find it, but not found.
You can take the solar intensity at Earth and scale it to the distance and size of Jupiter - again with the (visible) albedo to get the absorbed fraction.Ans said:And how much energy it receive from Sun?
I know it can be done. However, such result would not be precise, because some area have lower temperature, because of night or hurricanes, some area with higher temperatues. So I guess such approach can give only order of magnitude estimation.mfb said:Did you find its surface temperature and the Stefan-Boltzmann law?

I did it before start post, and even calculated it in mind, without calculator :)mfb said:You can take the solar intensity at Earth and scale it to the distance and size of Jupiter - again with the (visible) albedo to get the absorbed fraction.
