    Understanding Orbital Mechanics & Elliptical Paths

    Hi. I was playing a video game where, in one level, you are in an orbit around an attractor. The game was 2D, so there's no inclination, etc. The game showed the projected path of the body around the attractor. When you used the games controls to thrust in a direction, it would show the...

    Position of a Body on a Hyperbolic/Parabolic Orbit with Respect to Time

    Thanks. That doesn't really answer my question, but it's certainly a start. I can get the hyperbolic anomaly from the above formula; can I go from that to a true anomaly, and in the above formula, is M the same as for elliptical orbits? And does Barker's Equation also give a "parabolic anomaly"...

    Position of a Body on a Hyperbolic/Parabolic Orbit with Respect to Time

    Phew, that's a little beyond me. However, I know that it's certainly possible to plot a parabola/hyperbola in polar coordinates (or at least wikipedia says we can): r=a(e2-1)/(1+e*cosθ) Can I consider θ to be a true anomaly, and if so, is it possible to calculate θ from time t given...

    Position of a Body on a Hyperbolic/Parabolic Orbit with Respect to Time

    .. Using Keplerian Elements Hi. Disclaimer: this is the first foray into orbits I've ever taken. I only did mechanics in university and haven't really touched it sincew. I'm busy coding a simulation of a solar system. I've managed to code a routine to calculate the position of a body along...
