Sheesh, it's just semantics. Definitions are for communication, if they call them brown dwarfs then you know what they're talking about. The IAU's considered an object with a mass capable of fusing deuterium a brown dwarf, which is 13 Jupiter masses. Don't like it? Too bad, as long as it's qualified with "brown dwarf" then you know what they're referring to. So, the term "closest start to Earth" is another issue of semantics. In the context of this article, it means, "closest object outside of our own solar system with a mass over 13 Jupiters." Now, if they start handing out medals and big prize money to stars for being the closest to Earth, then go ahead and debate it, otherwise who cares?
