Burgasser et al. in wide-field search for T dwarfs using the Two Micron All Sky Survey (2MASS). DistanceCurrently the most precise distance estimate of 2MASS 1503+2525 is a trigonometric parallax, published by Dupuy and Liu in 2012: 157.2 ± 2.2 mas, corresponding to a distance 6.36 ± 0.09 pc, or 20.7 ± 0.3 ly.{{r|Dupuy2012}} 2MASS 1503+2525 distance estimates
