Astronomers have found over a thousand extrasolar planets now. How does our solar system compare? Thanks to the Kepler spacecraft, we now have a catalog of 1,235 alien planet candidates after just four months of operation. Of the 408 that have been found in multiple-planet systems, 170 of these containing two to six planets have been pictured in a “Kepler Orrery” posted by the Harvard-Smithsonian Center for Astrophysics. The press release says, “most of those look very different than our solar system”.
