... where dCJ is the distance from Callisto to Jupiter and dJE is the distance from Jupiter to Earth. We just calculated dCJ = 0.012 AU, and part (i) yields the range of possible dJE , between 4.2 and 6.2 AU. The angle will be greatest when dJE is smallest, so: θ = arctan(0.012/4.2) = arctan(0.0029) = 0 ...
