WISEPA J184124.74+700038.0 (designation is abbreviated to WISE 1841+7000) is a binary system of brown dwarfs of spectral classes T5 + T5,[2] located in constellation Draco at approximately 131 light-years from Earth.
WISE 1841+7000 was discovered in 2011 from data, collected by Wide-field Infrared Survey Explorer (WISE) Earth-orbiting satellite — NASA infrared-wavelength 40 cm (16 in) space telescope, which mission lasted from December 2009 to February 2011.
[2][1] Gelino et al. examined for binarity nine brown dwarfs using Laser Guide Star Adaptive Optics system (LGS-AO) on Keck II telescope on Mauna Kea; seven of these nine brown dwarfs were also newfound, including WISE 1841+7000.
Therefore, there are only distance estimates of this object, obtained by indirect — spectrofotometric — means (see table).
