QY Aurigae (QY Aur / GJ 268 / HIP 34603)^[7] ye un sistema estelar na constelación d'Auriga de magnitú aparente +11,47, visualmente asitiáu a 51 minutos d'arcu al sur de 63 Aurigae. Alcuéntrase a 20,0 años lluz de distancia y ye unu de los 100 sistemes más cercanos al Sistema Solar.^[8] Les estrelles conocíes más cercanes a esti sistema son Gliese 251 y GJ 1105, a 3,50 y 7,07 años lluz respeutivamente.^[9]

Coordenaes: 7^h 10^m 1.834^s, 38^° 31^′ 46.087^″

QY Aurigae ye una estrella binaria espectroscópica con un periodu orbital de 10,4280 díes. La órbita ye marcadamente escéntrica (ε = 0,34).^[10] Les dos estrelles que formen la binaria son nanes coloraes de tipu espectral M5V,^[10] siendo la so lluminosidá conxunta igual al 0,089% de la del Sol.^[11] Tienen mases envaloraes equivalentes al 17% y al 16% de la masa solar,^[8] siendo estrelles asemeyaes a YZ Ceti o Ross 614 A; esta postrera tamién forma parte d'una binaria de dos nanes coloraes, pero la separación ente dambes ye notablemente mayor.

Una o les dos estrelles de QY Aurigae son estrelles acandilantes^[12] —sufren erupciones que provoquen sópitos aumentos de rellumu—, carauterística común n'otres binaries análogues como Ross 614 o Luyten 726-8, siendo una componente d'esta postrera —UV Ceti— el prototipu de la clase.
