'Rogue' planet makes its own way in trip across the galaxy
11/15/2012In what sounds like a plot point from a new "Star Trek" movie, a rogue planet is spinning through the galaxy, beholden to no one. (Or at least to no stars.) Rogue planets are called that because unlike most (including Earth), they've somehow managed to avoid orbiting a star. This can make them difficult to discover, since most distant planets are identified by the effect they have on their star's light. From a field of "hundreds of millions" of planets, scientists found just one "homeless planet in our neighborhood." While we vote for naming it "Lone Ranger," the researchers opted instead for CFBDSIR2149-0403. [Source]
