Jupiter is 5.2 times farther than Earth from the sun. Find Jupiter's orbital period in earth years. Equation to use is: T^2 = Kr^3 Radius of earth is 6378100 m and radius of Jupiter is 71492000 m. I rearrange the equation to K = T^2/r^3 and set k of earth equal to k of Jupiter. I enter all of it including 5.2 times radius of earth into the equation. I solve for t of Jupiter but I always end up with 16.457 years when it should be 11.86 years. What am I doing wrong?
