It may sound like something from a very special episode of Doctor Who, but the Christmas planet is real. What's more, it's the most Earth-like world yet discovered. The planet, more properly known as Kepler 22-b, was revealed to the world Monday via a press conference at NASA Ames Research Center. It is one of thousands of planets discovered outside our solar system via the Kepler space telescope — and the first one that is slap-bang in the middle of what astronomers (really) call the Goldilocks zone: not too hot, not too cold, just right for life. So why call it the Christmas Planet? "It's a great gift," said William Borucki, the telescope's principal investigator, who came up with the seasonal name.
Actually making our way to the Christmas Planet might take a little longer, however. But we do know it's about twice the size of Earth, and that the average surface temperature is a balmy 72 degrees Farenheit. Coolest Bird On The Planet! BIGGEST EXPLOSIONS. Victoria's Secret Fashion Show - 2011.
