Homework Help: Orbiting Objects

  1. Dec 1, 2008 #1
    I have a question about orbiting objects. Maybe somebody could help me a little bit, because I don't know if I need to find other information to solve the problem and I'm not sure what equation I could use.

    If the average orbital radius is 2,5*1025 km, how long will it take to orbit the sun?

    Thanks a lot
