I think I found the answer after some searching, which I did try before which brought me here, but I think it is (T_A/T_B)^2=(R_A/R_B)^3

I just need an explanation of a formula, and I think part of it is wrong, so here is the formula: (T_A/T_G)^2=(R_A/R_B)^3 so T is the period and T_A is the period of planet A then below it is what I think is wrong, T_G G is the Kepler's constant, I'm not sure what that really is =...
