⟨Daedalus⟩ hi, is there a way to set a craft's exact orbit in principia?
<queqiao->
i used the cheat panel in stock and set the object's orbit by turning on hack gravity, but after i turned it off and used principia's orbital analysis, it gaves a different result from the orbit I set before. I guess this discrepancy is due to the difference between 2-body and n-body physics. So is there a way that I can directly place the craft in principia

⟨lpg4999⟩ no

⟨lamont⟩ "exact orbit" isn't a thing in principia (or in real life)
<queqiao->
⟨vevladdd⟩ You can't have an exact orbit. It'll change over time at least because planets are not round, and for many other reasons. In rl you can't "set" any orbits too. Maneuver your craft as precise as you can, and enjoy your achievement

⟨Daedalus⟩ i see. i was trying to replicate a GMAT mission in KSP, so that's y I am trying to place it at the same orbit that I inputed in GMAT
