WISE J000517.48+373720.5 is a brown dwarf of spectral class T9,[1][2] located in constellation Andromeda at approximately 23 light-years from Earth.[1]
Discovery
WISE J000517.48+373720.5 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. The discovery paper is not yet published.[2]
Distance
Trigonometric parallax of WISE J000517.48+373720.5 is not yet measured. Therefore, there are only distance estimates of this object, obtained by indirect — spectrofotometric — means (see table).
