The water-world planet is located in a system with at least 5 planets just 41 light years from Earth. The tidal-locking means that its orbit takes the same amount of time that it takes to rotate on its axis -- hence the same "side" of the planet is always facing the Sun. If Earth were tidally locked (which it is not), a particular side (say North and South America) would enjoy 24-hour days, while the opposite side (Asia) would be cloaked in perpetual darkness. This raises some interesting possibilities for 55 Cancri e. Based on new infrared light data collected from NASA's Spitzer Space Telescope, scientists have developed new insight into the alien world's climate. Cancri e's sun-facing side is a scorching 2,000 Kelvin (3,140 degrees Fahrenheit), with water existing in a super-critical state where it is found in localized, ever-shifting pockets of liquid and gas, topped with a thick blanket of steam. But the night side is likely cool and liquid.
