1. The problem statement, all variables and given/known data A comet is 10 times farther from the sun than the Earth. Find the time it take to make its orbit around the sun. 2. Relevant equations T^2/R^3 = K K= 3.36X10^18 3. The attempt at a solution I tried to create a ratio, but I honestly have no idea where to start. I'm not even sure I need to know kepler's constant for this problem. and the answer is T=31.6 I don't know what to put as R, and that leaves me with two variables, R and T. I also don't know if Kepler's constant is the same for the comet and the earth.
