Astronomers have pinned each of these monikers on brown dwarfs, a category that has always perplexed scientists because it raises questions about what it means to be a star or a planet.

Using the infrared capabilities of the <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/www.keckobservatory.org\/\">10-meter Keck II Telescope on Mauna Kea<\/a>, University of Hawaii researcher Michael Liu and his team estimated the brown dwarf&rsquo;s temperature, and have a ballpark range for its mass: between 6 and 15 times the mass of Jupiter.<\/p><p>It&rsquo;s special because it may be a class Y dwarf (temperature less than 225 degrees Celsius (440 F)), a type of object whose existence astronomers had predicted but never actually found.
