I'd check for a slight breeze, indicating I was on an escalator. :smile:

It turns out this can be solved geometrically. Solution 1: The eccentricity vector points at the periapsis, so the directrix of the parabola is perpendicular to the eccentricity vector. Since the distance from the planet to the rocket is equal to the distance from the rocket to the directrix...

I wrote a game with a rocket that orbits a planet, and you can change the orbit with thrusters. As part of it I draw the predicted orbit for the rocket. To do this I compute the eccentricity vector, then the eccentricity e, then the major and minor axis of the ellipse or hyperbola as...
