    Astronomy/physics question

    My physics prof. asked us this question and I don't know how to approach it. Can anyone suggest a nice way to set this type of problem up?

    Calculate the period of Procyon B's revolution about Procyon A in years.

    What info do I need to get first? What kind of equations will I be using to solve this?

    It's been a long time since I've done physics. I believe that Newton's law of universal gravitation would be helpful along with
    knowing the distance and masses involved.

    ... some given orbital data and Kepler's 3rd law of planetary motion.
