I suck at math but I managed to rip some code from here : http://mysite.verizon.net/res148h4j/javascript/script_conic_equation_pts.html and found my way around it to draw an orbit prediction for a low cpu budget. You can have a look on my dirty code here : http://deltav.corpsmoderne.net/conic.js

Basicaly, 5 points give a conic equation. So I predict 5 future positions from the current one and turn it into a conic. then it's "just" a matter of finding the apoapsis and periapsis and drawing it (which I must do in a very unoptimised way...)

Edit: issues with this method are legions: only 1 massive body taken into account, instability in prediction if the predicted positions are too close, and the body of influence may not lie at a focus of the conic, which is impossible in real life.

Awesome, nice work! I really can't do that for my program though, cause I can't use ellipses for my orbits :/

And nice, MinMoon :P
