'Orbital Oddities - Strange goings-on with 3 or more bodies' - Lagrange points, resonances, Roche limits, lots of odds and ends (with simulations).
The areas discussed include:
Lagrange Points | Definition of the 5 Lagrange points; Trojans; Sun-Earth system; Earth-Moon system; Uses - satellites, trajectories |
Roche Limits | How a body is broken up by gravity; The 4 major planets |
Rings | Stability; Gaps; Shepherd Moons; Spokes on Saturn's Rings |
Strange Orbits | Horseshoe orbits; Spiralling horseshoes; Cruithne; Co-orbits; Klemperer Rosettes |
Orbital Resonances | Instability; Kirkwood Gaps; Ceres; Stability; Galilean Moons - Laplace resonances; Titius-Bode Law |
Rotational Resonances | Moon; Mercury; Venus; Pluto |
Roche Lobes | Back to the Lagrange L1 point where we started |
