V1285 Aquilae (V1285 Aql / GJ 735 / HIP 92871)^[7] ye un sistema estelar na constelación d'Aquila de magnitú aparente +10,18. Asitiáu a 37,8 años lluz del Sistema Solar, la estrella conocida más cercana a esti sistema ye Gliese 740, distante 2,29 años lluz.^[8]

Coordenaes: 18^h 55^m 27.41^s, 8^° 24^′ 9.031^″

V1285 Aquilae ye una estrella binaria formada por dos nanes coloraes de tipu M3.5 Ve. Ye una binaria espectroscópica —asemeyada a EQ Pegasi, DF Ursae Majoris o GU Bootis— con un periodu orbital de namái 7,658 hores. La distancia media aparente ente dambes estrelles ye de 0,04 UA, una décima parte de la distancia que dixebra a Mercuriu del Sol. La órbita ta inclinada 32º respectu al planu del cielu.^[9] El sistema apaez catalogáu como estrella acandilante nel General Catalogue of Variable Stars^[10] y dambes estrelles son cromosféricamente actives.^[9]

Los dos componentes tienen carauterístiques físiques bien similares. Tienen 0,32 y 0,30 mases solares y aproximao el mesmu tamañu, equivalente al 44% del radiu solar. Les velocidaes de rotación respeutives son 4,50 y 3,60 km/s.^[9] La so lluminosidá conxunta apenes supón el 0,95% de la lluminosidá solar.
