Mars travels around the Sun in 1.68 Earth years in an approximately circular orbit with a radius of 2.18 x 10^8 km. Determine the mass of the Sun.

Fairly easy, I know most of how to do it but I keep getting wrong answers. Help me out a bit? Thanks!

Ok well you can you can set Fg equal to Fc.

Fg = Fc

G msmm/r2 = mm2r/T2

Simplifies to

G Ms = 4π2r3/T2

So

(6.67x10-11) Ms = 4(3.14)2(2.18x1011)3/(52980480)2

Ms = UDOIT kg
