HD 224635 in HD 224636 je par zvezd, ki oblikujeta binarni zvezdni sistem v ozvezdju Andromede. Od nas sta oddaljeni približno 94 svetlobnih let,[11] ena okoli druge pa se obkrožita na vsakih 717 let.[12]

Primarna zvezda je HD 224635 z magnitudo 6,46[12] (kar jo postavlja na seznam zvezd, ki so vidne s prostim očesom le pod najboljšimi pogoji) in s spektralnim razredom F8.[13] Je 1,19-krat masivnejša od Sonca.

Sekundarna zvezda, ki je rahlo temnejša, je HD 224636 z navidezno magnitudo 6,72[12] in spektralnim tipom G1.[13] Je 1,13-krat masivnejša od Sonca.[13]
