WISE J031624.35+430709.1 is a brown dwarf of spectral class T8,[1] located in constellation Perseus at approximately 106 light-years from Earth.[1] It is one of the furthest T-class brown dwarfs known.


WISE J031624.35+430709.1 was discovered in 2012 by Mace et al. from data, collected by Wide-field Infrared Survey Explorer (WISE) Earth-orbiting satelliteNASA infrared-wavelength 40 cm (16 in) space telescope, which mission lasted from December 2009 to February 2011. The discovery paper in not yet published.[2]


Trigonometric parallax of WISE J031624.35+430709.1 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect — spectrofotometric — means (see table).
