    Alien Solar Systems Are Much Different Than Our Own
    NASA's Kepler spacecraft has discovered 170 planetary systems containing between two and six transiting planets. This graphic shows all the multiple-planet systems discovered by Kepler as of 2/2/2011; orbits go through the entire mission (3.5 years). Hot colors to cool colors (red to yellow to green to cyan to blue to gray) indicate big planets to smaller planets, relative to the other planets in the system.

    Alien solar systems with multiple planets appear to be common in our galaxy, but most of them are quite different than our own, a new study finds.

    NASA's Kepler Space Telescope detected 1,235 alien planet candidates in its first four months of operation. Of those, 408 reside in multiple-planet systems, suggesting that our own configuration of multiple worlds orbiting a single star isn't so special.

    What may be special, however, is the orientation of our solar system's planets. Some of them are tilted significantly off the solar system's plane, while most of the Kepler systems are nearly as flat as a tabletop, researchers said.
