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.^[3]

Distance

Currently the most accurate distance estimate of WISE J031624.35+430709.1 is a trigonometric parallax, published in 2019 by Kirkpatrick et al.: 13.6+0.5
−0.5 pc, or 44.5+1.8
−1.6 ly.^[2]
