Discovery
WISE 0713−2917 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 discovery of seven new found by WISE brown dwarfs of spectral type Y, among which also was WISE 0713−2917.[1]:{{{3}}}
Distance
Trigonometric parallax of WISE 0713−2917 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect—spectrophotometric—means (see table).
