Internal physics links:
- Many pages simulating gravitational interactions:
- Klemperer Rosettes, very wierd but
inherently stable orbits where many objects share the same orbit.
- Cruithne, Earth's second moon, an
asteroid in a horseshoe orbit (a 1::1 resonance with Earth).
- Stable Figure-Eight Orbits, a figure
eight orbit of three equal-weight bodies, originally discovered by
Cristopher Moore, with these coordinates derived by Carles Simo
- Other orbits by Carles Simo:
- Those same orbits, but running them longer to show any instability:
- A three-dimensional 12-body orbit by
Cristopher Moore and Michael Nauenberg, 2005, and a 4-body one too.
- Stable orbits around binary stars, showing
some 2::1 and 3::1 resonances for inner planets of binary star systems.
- Noncolliding orbits that fill
3-space and keep neighbors next to neighbors.
- Dyson swarms, some built out of those
noncolliding orbits above.
- Globular Cluster, just 200 random
objects interacting gravitationally.
- Globular Cluster with Trails, same
- Limits of the L4 Lagrange point
- Exploring Orbits with Java, answering
most of the basic questions about orbits.
- A scale model of the solar system.
- Rings formed by a planet, a moon, and an
asteroid in 5:3 resonance with the moon..

a little project with ropes and pulleys
