WISE 1738+2732 was discovered in 2011 from data, collected by the
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. WISE 1738+2732 has two discovery papers:
Kirkpatrick et al. (2011) and
Cushing et al. (2011), however, basically with the same authors and published nearly simultaneously. •
Kirkpatrick et al. presented discovery of 98 new found by WISE
brown dwarf systems with components of
spectral types M, L, T and Y, among which also was WISE 1738+2732. • Cushing
et al. presented discovery of seven brown dwarfs—one of T9.5 type, and six of Y-type—first members of the Y spectral class, ever discovered and spectroscopically confirmed, including "archetypal member" of the Y spectral class
WISE 1828+2650, and WISE 1738+2732. These seven objects are also the faintest seven of 98 brown dwarfs, presented in
Kirkpatrick et al. (2011). Currently the most accurate distance estimate of WISE 1738+2732 is a
trigonometric parallax, published in 2021 by Kirkpatrick
et al.: , corresponding to a distance of , or . WISE 1738+2732 has a proper motion of milliarcseconds per year. ==Properties==
