Kepler Finds Bizarre Systems
RedEaredSlider writes "The Kepler Space Telescope has run across some truly bizarre solar systems. Among the candidates: a system with full-on planets orbiting in a Trojan configuration, one with planets that all orbit their planets in less than 10 days, and one in which resonances between small and large worlds essentially keep the thing together."
I was having trouble imagining the 8:6:4:3 resonance pattern, so I dug out this very cool visualisation: http://www.princeton.edu/~rvdb/WebGL/KOI-730.html (needs a WebGL-capable browser, for some reason FF 4 doesn't work though).
