A brown dwarf is A) a tepid spot of tea; B) a tiny cup of java; or C) a star with so little energy its temperature isn’t much different from a cup of coffee or tea. The correct answer — C — describes a newly discovered, lukewarm star about 75 light years — 709,539,630,000,000 kilometers or 440,887,486,000,000 miles — from Earth. Wishing upon this star, however, might be difficult. Unromantically dubbed “CFBDSIR J1458+1013B,” it is the coldest and faintest star ever found, astronomers say, with a surface temperature not much higher than 100 degrees Celsius.
