Summary
DescriptionClassical Kepler orbit e0.6.gif
GIF animation of a Kepler orbit with eccentricity 0.6. Once perfected, this will be the basis of several related animations for orbital precession, Newton's theorem of revolving orbits and the Laplace-Runge-Lenz vector.

I made this image using Blender and the classical Kepler equations using the eccentric anomaly, described in the classical mechanics textbook of Herbert Goldstein. The numerical values of the radius and angle as a function of time were calculated by my own GPL computer program.
