Daniel Fabrycky from the Kepler science team put together a visualization of all the multiple-planet systems discovered by the Kepler spacecraft as of February of 2011. This second version illustrates the planet candidates found as of Feb 2012: 885 planet candidates in 361 systems—double the number of systems in the original Kepler Orrery. The orbit radii are to scale with respect to each other and planet sizes are to scale with respect to each other, but orbits and planet sizes are different scales. The colors are in order of semi-major axis: two-planet systems (242 in all) have a yellow outer planet; 3-planet (85) green, 4-planet (25) light blue, 5-planet (8) dark blue, 6-planet (1, Kepler-11) purple.
