PASADENA, Calif., Oct. 27 (UPI) -- New observations using the U.S. space agency's Spitzer Space Telescope indicate the nearest planetary system to ours has two asteroid belts.
The National Aeronautics and Space Administration said the star at the center of the nearby system, called Epsilon Eridani, is a younger, slightly cooler and fainter version of the sun. Previously, astronomers had uncovered evidence for two possible planets in the system, and for a broad, outer ring of icy comets similar to our own Kuiper Belt.
