WISE J035000.32−565830.2 (designation abbreviated to WISE 0350−5658) is a brown dwarf of spectral class Y1, located in constellation Reticulum, the nearest known star/brown dwarf in this constellation. Being approximately 11.2 light-years from Earth, it is one of the Sun's nearest neighbors.
WISE 0350−5658 was discovered in 2012 by J. Davy Kirkpatrick and colleagues from data collected by the Wide-field Infrared Survey Explorer (WISE) in the infrared at a wavelength of 40 cm (16 in), whose mission lasted from December 2009 to February 2011. In 2012 Kirkpatrick et al. published a paper in The Astrophysical Journal, where they presented the discovery of seven new brown dwarfs of spectral type Y that had been found by WISE, among which was WISE 0350−5658.
WISE 0350−5658 is one of the nearest known brown dwarfs: its trigonometric parallax is 0.291 ± 0.050 arcsecond, corresponding to a direct inversion distance of 3.44+0.71
−0.5 pc (11.2+2.3
