GeeKay Posted December 15, 2021 Share Posted December 15, 2021 I used to have an excellent online calculator that enabled me to show the possible orbits of a satellite around a larger secondary body (e.g. a moon) which itself was in orbit around (say) a planet. Unfortunately my local PC repair shop unwittingly deleted the calculator during a refurb. And since I can't recall the scientific/technical term for this "three-body" gravitational arrangement, I'm no longer able to locate online the calculator in question. I would therefore be very grateful if anyone can help me here. PS. Unhappily I don't have anything like the mathematical skillset to do these calculations by hand. Thanks in advance.
