2MASS J18450079-1409036

2MASS J18450079−1409036 och 2MASS J18450097−1409053 är ett system av två röda dvärgstjärnor som båda har spektraltyp M5, med ett projicerat avstånd av 3,2 bågsekunder. Systemet är beläget i stjärnbilden Skölden på ett avstånd av 18,2 parsec (59 ljusår ) från solsystemet. Kinematiskt tillhör det den unga (30-50 miljoner år) Argusföreningen.

2MASS J18450079−1409036 och 2MASS J18450097−1409053 som verkar vara ett vanligt egenrörelsepar, bekräftades år 2016 vara gravitationellt bundet.
