The Christmas Planet
This month a planet, properly known as Kepler 22-b, was revealed by NASA.
They have discovered thousands of planets outside our solar system using the Kepler space telescope, but this one is the most Earth-like world discovered so far.
It is located in an area nicknamed by astronomers the Goldilocks Zone. That's because it's not too hot, not too cold, but just right for life.
And the planet has been nicknamed the Christmas Planet because three photos of a planet are needed from Kepler to be sure that 22-b was for real. A 22-b year is 290 days long and photo number three came during the 2010 holiday season, so...
The Christmas Planet is 600 light years away. It is about twice the size of Earth. The average surface temperature is 72 degrees Fahrenheit, which sounds pretty nice right now.
