Kepler-11 and Six Orbiting Planets

From here:

NASA’s Kepler space telescope watches a star, Kepler-11. The star appears to blink in a pattern. It dims like clockwork as six “hands” of differing size orbit around it at different rates. Kepler-11 dims when its six orbiting planets cross between it and the Kepler spacecraft. Calculations show the planets are nested in circular orbits that lie in almost the same plane.
