WISE 0350−5658
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 17.7 light-years from Earth, it is one of the Sun's nearest neighbors. Discovery. 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. Distance. WISE 0350−5658 is one of the nearest known brown dwarfs: its trigonometric parallax is 0.184 ± 0.010 arcsecond, corresponding to a direct distance of 5.4 pc (17.7 ly). See also.
