1. The problem statement, all variables and given/known data "The mass of a star is 4.85x10^29kg. In scientific notation, Kepler's constant for that star is bx10^w s2/m3. the value of b is_____." 2. Relevant equations K=T2/r3 3. The attempt at a solution This problem is very tough. I first assumed that K would be 0 because the star has no satellites, and therefore is experiencing linear motion, not circular motion. To my dismay however, the answer is indeed 3 digits and Kstar> 0. The greatest obstacle is how am I to derive the period and semi major axis of its orbit, if i am only given the star's mass???!!! Any insights into this problem are helpful. Thanks!
