WISE 1828+2650 (full designation is WISEPA J182831.08+265037.8) is a brown dwarf, located in south-west corner of constellation Template:Constel. It is one of six Y-type brown dwarfs (along with WISE 0410+1502, WISE 1405+5534, WISE 1541-2250, WISE 1738+2732 and WISE 2056+1459) among 106 brown dwarfs (counting components of two binary systems[3]), discovered in 2011 by the Wide-field Infrared Survey Explorer. With temperature below 300 K[2], it is currently the coolest known brown dwarf. Also it has the latest known spectral class (>Y0[2]), and is identified as the "archetypal member" of the Y spectral class.[2] The photometric distance estimate of this object is <9.4 pc (<30.7 ly).[1]
