The period of a comet orbit is 100 years. As its closests approach is 0.37 AU from the sun. What is the semi-major axis of the comet's orbit? How far does it get from the sun?


2. Homework Equations

(T1/T2)^2 = (s1/s2)^3

3. The Attempt at a Solution
I dont even know where to begin with this problem any help would be really appreciated.
