WISEA 1101+5400 (full name WISEA J110125.95+540052.8) is a T-type brown dwarf (specifically T5.5) approximately 100 light-years away in the constellation Ursa Major. 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 star. It is the first confirmed brown dwarf found by the project.
