The temperature of a satellie's surface

    Can somebody tell me how hot or how cold (appr.) the outer surface of an Earth satellite can be?
    Thank you

    Very hot or very cold depending ot whether or not it is facing the sun or not.
    Also, the side facing the sun can get significantly hotter than the side facing away from the sun.
    Thermal management is a big issue is satellite design, cooling can be a big problem since there is very little convection in orbit.
    So I don't think there is a general answer to your question.
