Hi,
    I have a question on Newton Universal Gravity. According to the
    formula  g=GM(Mass of Earth) / Radius of the earth. In this formula
    we know that g=9.81 m/s^2 and the value G=(5 x 10^-11) and the
    radius of the earth is approx 6380 Kilometers, so we can compute and
    get the mass of the earth as approx (5 x 10^24 Kg). To calculate the
    mass of earth we had three knowns and one unknown, but let's say I
    want to calculate the mass of the planet Mars. In this case I only
    have two knowns (G=5 x 10^-11, and the radius of Mars -> Which I am
    not sure how to obtain, but probably can get the data from an
    astronomy book), So in this case how can I compute the gravity g in
    Mars and the Mass of the planet Mars. Thanks in Advance.
