Spectral type T5.5±0.5. Dupuy et al. (2019) calculate a mass of 66 ± 4 M_Jup. Faherty et al. (2020) list the substellar companion with a lower mass estimate (~36 M_Jup) compatible with an assumed age equal to or lower than 3 Gyrs.

Among the closest substellar binaries to Solar System. Dupuy et al. (2019) estimated that the Scholz's Star passed within 68,700 ± 2,000 AUs of the Sun in Late Pleistocene times (80.5 ± 0.7 kyr ago) passing through the outer Oort Cloud.
