Asteroid Belt Discovered Around Our Sun's "Twin"

loid_void writes "that the National Geographic is reporting evidence of a massive asteroid belt around a "twin" of our own sun has been found. Kim Weaver, a Spitzer Space Telescope scientist, said the finding marks "the first time that scientists have found evidence for a massive asteroid belt around a mature, sunlike star." "This region around the star is the sort of place where rocky planets [like Earth] may form," The star, dubbed HD69830, is some 41 light-years away--which, in space terms, is practically our own backyard. Part of the constellation Puppis, the star is a tad too faint to see with the unaided eye."

"It is thicker than the asteroid belt in our own solar system, which lies between Mars and Jupiter and packs nearly 25 times more debris."
