Brown Dwarf Star 7.2 Light Years Away

In stars it's not the size of the ship it's... Ok we won't go there, but not all stars are built the same and this is definitely true for this quiet guy.
Brown dwarf stars start hot like the rest but lack the pressure to continue feeding the center of the star and ultimately the fusion process stops. When this happens the star gets colder and fizzles out creating what is larger than typical gas planets.
We've known that this can happen and in fact we have found one very cold and very close to our solar system. Just 7.2 light years away our star like neighbor is called WISE J085510.83-071442.5. What a nice name huh? It was found by the Wide-field Infrared Survey Explorer which creates names for discoveries based on coordinates in the sky.

All in all that puts this star about number 7 in the closest stars to our sun and leads us to ask what else are we missing if J0855 was that close?
