WISEPA J174124.26+255319.5 (designation is abbreviated to WISE 1741+2553) is a brown dwarf of spectral class T9, located in constellation Hercules at approximately 18 light-years from Earth.

WISE 1741+2553 was discovered in 2011 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. WISE 1741+2553 has three discovery papers: Scholz et al. (2011), Gelino et al. (2011) and Kirkpatrick et al. (2011).

Currently the most accurate distance estimate of WISE 1741+2553 is a trigonometric parallax, measured using Spitzer Space Telescope and published in 2013 by Trent Dupuy and Adam Kraus: 0.180±0.015 arcsec, corresponding to a distance 5.6+0.5
