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 ...

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.

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 ...
