Celestial Mechanics
Compute the orbital period of a massive body orbiting another:
Kepler's third law, 4 solar masses, 5 Earth masses, 2.5 AU
Interactively compute the orbital speed of a body:
circular orbit speed
Visualize the relation between the eccentric and true anomaly:
mean anomaly 85 degrees eccentricity 0.6
Compute locations of Lagrange points:
Lagrange points Earth and Moon
Investigate the relationship between orbital distance and phase:
orbital radius with eccentricity 0.7 and semimajor axis 17.8 AU
