1. The problem statement, all variables and given/known data Determine Kepler's constant for all Earth Satellites. No information is given, only the question. 2. Relevant equations K=R³/t² 3. The attempt at a solution I decided to use the moon as a satellite. So I went K=(384,403,000)³/(2,360,594.88)² For R I used the distance from the moon to earth in meters (384,403km) and for t I used the time it takes the moon to revolve around earth in seconds (27.3 days). The answer I get is 1.02x10¹³. The answer is supposed to be 9.85x10¹² Thanks for any help!
