An astronomer observes a binary star over some time. The masses of the stars are found to be 9.00 M, for star Aand 7.00 A, for star B. On closest approach, the separation between the stars is 3.60 x 10** m, and the largest distance between the stars as they orbit each other is 4.50 x 10** m. Calculate the orbital period of the binary system, in years. Enter the orbital period in years. .1'1{_gun =1.99x 1030 kg
