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.

Discovery

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 satellite — NASA infrared-wavelength 40 cm (16 in) space telescope, which mission lasted from December 2009 to February 2011. In March 2013, the discovery paper was published.[2]

Distance

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).
