Temperature and orbital period

    1. The problem statement, all variables and given/known data
    Hi everyone,

    was hoping someone could help me to answer a question:

    an ateroid has an equilibrium temperature measured as 200 K. What is the object's orbital period around the Sun?

    That is the exact wording of that particular question and that's why I am a little stumped.. it also says to base it upon your considerations in question #4, which reads

    assuming the Earth's radius is 637 km, the solar constant is 1370 w/m2, and our planetary albedo is 0.31, then:
    (a) determine total power entering Earth's atmosphere
    (b) the total power that would be asborbed in the absence of an atmosphere
    © surface temperature assuming it radiated into space all the energy it absorbed

    2. Relevant equations

    3. The attempt at a solution

    I guess you have to just find a relationship btw the variables caracterising the asteroid knowing it is in circular orbit of radius R and that the asteroid is a ball of radius r, mass m and its temperature is 200K.
