[2][1] It was discovered in March 2017 by members of the citizen science project Backyard Worlds.

Initial photometric analysis suggested it was a T5.5 dwarf, which was later confirmed by a spectrum of the object obtained with the NASA Infrared Telescope Facility.

The brown dwarf was identified by several volunteers, including the therapist Rosa Castro, Bob Fletcher, Khasan Mokaev and Tamara Stajic.

The team estimated that the project would discover 37+39−21 new L-dwarfs, 77+41−31 T-dwarfs and 6+7−4 Y-dwarfs.

[1] As of July 2019 the project did meet this estimate with spectroscopically confirmed T- and L-dwarfs (70 T-dwarfs and 61 L-dwarfs), but exceeded this estimate by brown dwarf candidates (1305).
