About a year ago, Daniel Fabrycky from the Kepler spacecraft science team put together a terrific orrery-type visualization of all the multiple-planet systems discovered by the Kepler spacecraft as of February of 2011. With a new round of exoplanets just announced, here’s part two. This one is a visualization of the planetary systems discovered by Kepler that have more than one transiting object. There are 885 planet candidates in 361 systems, doubling the number of systems in the original Kepler Orrery. In the description of this video, Fabrycky says the orbits are to scale with respect to each other, and planets are to scale with respect to each other. The colors are in order of semi-major axis, and 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.
Watch and enjoy!
And as a reminder, we’ll be doing a live interview on Friday, March 2 to talk about the latest exoplanet discoveries by Kepler!
