Re: Getting constrained orbits

This group seems to be on holidays!

Well, thanks to it, I could see my question was already answered at http://www.projectpluto.com/find_orb.htm#Convergence_problems

But I have yet to figure out how to get R1 and R2 from a single distance at a given date.

Thanks for any hint!

But sometimes, what you got to offer Find_Orb in order to make things easier is distance. Distance to Solar system minor planets can be determined via parallax using two observers in the surface of Earth imaging the object at the same time.
