The following equation, derived from Newton's version of Kepler's third law, allows us to calculate the mass (MMM) of a central object, in solar masses, from an orbiting object's period (ppp) in years and semimajor axis (aaa) in astronomical units: M=a3p2M=a3p2 Using this formula with the values you found in Parts C and D, what is the approximate mass of the central object?
