1. The problem statement, all variables and given/known data A newly discovered asteroid orbits at twice the Earth-Sun distance. Find its period of orbit (in years). 2. Relevant equations I know that I'm supposed to use Kepler's third law to determine this. T2 = Kr3 K = 4∏2/GM and the Earth-Sun distance is of course 1 Au 3. The attempt at a solution I know that the answer should be √8 or about 2.83 years I just don't know how to get there. So frustrating because I know that this is a simple question. Could it be that K = 1, and R=2 therefore R3 = 8?
