Coldest Brown Dwarf

April 30, 2014
This artist's conception shows the object named WISE J085510.83-071442.5, the coldest known brown dwarf. This cool star-like body is as frosty as the North Pole (or between minus 54 and 9 degrees Fahrenheit). It is also the fourth closest system to our sun, at 7.2 light-years from Earth.
