WISE J035000.32-565830.2 (abbreviated name: WISE 0350-5658 ) is a brown dwarf of the spectral class Y1 in the constellation Netz . At a distance of about 12 light years , it is one of the Sun's closest neighbors .

discovery

WISE 0350-5658 was in 2012 by the American astronomer J. Davy Kirkpatrick and his colleagues of the data based on the Space Telescope Wide-field Infrared Survey Explorer (WISE) discovered that, between December 2009 and February 2011, a survey in the infrared at a wavelength of 40 cm performed. In 2012, Kirkpatrick et al. in the Astrophysical Journal the discovery of seven brown dwarfs of spectral class Y newly found by WISE, among which WISE 0350-5658 was.

The other brown dwarfs discovered by the research group in 2012 are WISE 0146 + 4234 (Y0), WISE 0359−5401 (Y0), WISE 0535−7500 (≥Y1), WISE 0713−2917 (Y0), WISE 0734−7157 (Y0) , WISE 2220-3628 (Y0).

distance

WISE 0350-5658 is one of the closest known brown dwarfs. His Trigonometric Parallax , published by Marsh et al. (2013), is 0.291 ± 0.050 arc seconds , corresponding to a distance of 3.7 ^+1.6_−0.4 Parsec (12.1 ^+5.2_−1.3 Light years).
