    How much energy radiate Jupiter?
    I tried to find it, but not found.
    And how much energy it receive from Sun?

    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.
    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.

    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.
    Luminocity of Sun is described in many places, thermal balance of Earth too. I am sure Jupiter's thermal balance is also well described, but not know where it is described.
    I did it before start post, and even calculated it in mind, without calculator :)
    However, it is also very imprecise result.

    If you are interested in more precise numbers, looking for "jupiter energy balance" at google leads to tons of publications.

    Thanks, seems as I used incorrect phrase for search
