hi svqweasdzxc! welcome to pf!

relative angular velocity of A relative to B is dθ/dt, where r and θ are the position of A, measured in a polar coordinate system whose origin is at BI am not clear about the concept about relative angular velocity.

(or, more realistically, it's the angular speed with which

try to move the problem from angular speed to "linear" speed. The Earth moves with speed V

Now, the "linear" speed can be rewritten as the angular speed times the radius, so we can write the relative speed as the distance between Earth and KBO multiplied by the relative angular speed (V

(Note that this is true only in the case opposition or if r>>1)

I apologize for (really) possible English mistakes, I need a bit of training about that.
