"Time of Periapsis Passage" In AlexMoon Launch planner?

[dlrk]

I'm trying to add an asteroid as a vessel in the Alex Moon launch planner(https://alexmoon.github.io), and it asks for Time of Periapsis Passage. I'm not sure what this date is, since the time of periapsis passage changes every orbit.

It just needs one, so it knows where in the orbit the asteroid is.

If you don't put any time in, all the planner can know is that the asteroid is somewhere on the orbit. When you put in any time, the planner can look forward and see where the asteroid is in all future orbits. And back, I presume, if it was coded that way.

Thanks, I got it now!
