In 2MASSW J0920122 + 351 742 (also with 2MASS J09201223 + 3517429 , or 2MASS J0920 + 3517AB called) is probably a triple system. Spectroscopically, the system can be separated into two components with the approximate spectral classes L5.5 and L9.0. Due to the mass estimation of the less luminous component, however, it can be assumed that this is itself a double system that has not yet been resolved.
