It was discovered in 2000 by I. Neill Reid et al. 2MASS 0036+1821 is of spectral type L3.5, the surface temperature is 1300-2000 Kelvin. As with other brown dwarfs of spectral type L, its spectrum is dominated of metal hydrides and alkali metals. Its position shifts due to its proper motion by 0.9071 arcseconds per year. See also
