Jupiter’s Trojan asteroids fulfill the prediction of Lagrange that orbits can be stable when a small body orbits in specific locations relative to its ‘parent’ planet and the Sun. The first such Trojan asteroid was discovered ...

Physics distance education has grown rapidly in recent years. The theory part of a physics course taught in this way has much common ground with other courses. However, lab instruction is an important part of introductory ...

By studying orbits of near-Earth asteroids potentially in 2:3 mean motion resonance with Earth, Venus, and Mars, we have found plutino analogs. We identify 23 objects in the inner solar system dynamically protected from ...

Presentation from CASCA 2006 covering general aspects of co-orbital motion with emphasis on the fact that they would be good targets for space missions.

Presentation about stability of quasi-satellites, no movies.
