WASHINGTON, April 28 (UPI) -- If Earth orbited WISE J085510.83-071442.5, a nearby star newly discovered by NASA scientists, there would likely be no such thing as a bathing suit or short shorts. That's because this "brown dwarf" -- a star too small to enable nuclear fusion and radiate light -- is as cold as the Arctic.
With its temperature fluctuating between minus-54 and 9 degrees Fahrenheit, the star is the coldest ever spotted. Because brown dwarfs give off minimal light and heat, they're extremely hard to find without a telescope outfitted with an infrared lens. Astronomers have detected other brown dwarfs, but their temperatures have been around room temperature.
