| Mar 3, 2020 at 19:55 | comment | added | notovny | I would say, "Yes, The equations for going from Mean Anomaly to Eccentric Anomaly to True Anomaly are indeed different for hyperbolic orbits than for elliptical ones, if that's part of your process." The biggest differences are sign-flipping on some of the terms, and the use of hyperbolic trigonometric functions rather than the circular trig functions. | |

| Mar 3, 2020 at 18:21 | comment | added | DrBunny | @lancew This is an excellent question because 1) it is fundamental to space exploration. "Buzz" Aldrin acquired his nickname for his incessant talk of orbital mechanics. He did his doctoral thesis on orbital rendezvous techniques at MIT. 2) It points up the paradigm shift in engineering and science brought about by digital computers. Assuming closed form solutions to differential equations is no longer required. | |

| Mar 3, 2020 at 15:27 | comment | added | lancew | That was not my intent, thank you for the feedback. I think I boiled the problem down enough, hopefully I didn't remove any pertinent information. | |

| Mar 3, 2020 at 15:08 | comment | added | peterh | I think the site should be more lenient with programming questions if the essence of the problem is about astronomy and not programming, and I feel a strong motivation to vote it so. However, your problem looks like a "debug my code for me" problem. This is nowhere welcomed, not on the StackOverflow and not here. I click now "Skip" (this is a moderation vote, what to do with your question), but please improve your post ASAP. | |
| Mar 3, 2020 at 14:54 | comment | added | uhoh | There are one or two "please debug my space exploration code for me" questions here a year, and their problems are almost never resolved here. | |

| Mar 3, 2020 at 14:19 | comment | added | lancew | Could you please provide some information on what you mean by 'failing to fit conic sections?' I vaguely understand that these trajectories are based on math by slicing a cone with a plane, but I couldn't draw any equations from that myself. Perhaps I could solve my problem if I understood this part better. | |
| Mar 3, 2020 at 14:14 | comment | added | Carl Witthoft | If you remove the details about orbits and limit yourself to the problem of failing to fit conic sections (i.e. getting an illegal semimajor axis), you'll find this is exactly a pure coding problem. | |
| Mar 3, 2020 at 14:10 | comment | added | lancew | The medium may be code, but the problem is very much space/physics related. Most people on StackOverflow would look at this and say 'you're in the wrong place.' | |
| Mar 3, 2020 at 14:07 | comment | added | Carl Witthoft | recommend closing as this is a coding question and not related to issues of space | |
