WISEPC J150649.97+702736.0 (designation abbreviated to WISE 1506+7027, or WISE J1506+7027) is a brown dwarf of spectral class T6, located in constellation Ursa Minor.〔The nearest known star/brown dwarf in this constellation.〕 Being light-years from Earth, it is one of the Sun's nearest neighbors. Brown dwarfs closer to the Sun include Luhman 16 and WISE 0855−0714. Other brown dwarfs that may be closer to the Sun include ε Indi Ba and ε Indi Bb at 11.8 light-years and WISE 0350-5658 at light-years. ==Discovery== WISE 1506+7027 was discovered in 2011 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 2011, Kirkpatrick and colleagues published a paper in The Astrophysical Journal Supplement, where they 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 1506+7027.〔These 98 brown dwarf systems are only among first, not all brown dwarf systems, discovered from data, collected by WISE: six discoveries were published earlier (however, also listed in Kirkpatrick et al. (2011)) in Mainzer et al. (2011) and Burgasser et al. (2011), and the other discoveries were published later.〕
