If the planet is 6 times further away than the two stars are from each other, then the angle is about 9.5 degrees (2 * tan^-1(0.5 * 1 / 6)). You split the sun-sun distance in half to get 2 right triangles, do th...

One could prove that it's impossible to do with 4 satellite passes if one could find a set of 9 states such that no three of them were colinear (i.e., you couldn't cover any 3 of the 9 in a single satellite pass). By the Pigeonhole Principle, we'd need at least 5 passes to cover these 9 states (and ...
