Gliese 687 (GJ 687 / LHS 450 / HIP 86162)^[9]^[10] ye una estrella cercana asitiada a namái 14,77 años lluz del Sistema Solar. Visualmente alcontrar na constelación de Draco a 25 minutos d'arcu de ω Draconis.

Gliese 687 ye una nana colorada de magnitú aparente +9,15 non visible a simple vista, que la so lluminosidá ye equivalente al 0,4% de la que tien el Sol. Pertenez al tipu espectral M3V y tien una temperatura superficial de 3237 K.^[11] La so masa apenes supón el 41% de la masa solar^[11] y el so radiu ye daqué menor de la metá del radiu solar.^[12] Xira sobre sigo mesma con una velocidá de rotación proyeutada igual o inferior a 2,8 km/s.^[11] El so metalicidá, espresada como la rellación ente'l conteníu de fierro y el d'hidróxenu, ye comparable a la solar ([Fe/H] = 0,00).^[13] Amuesa un movimientu propiu grande al traviés del cielu, avanzando 1,304 segundos d'arcu cada añu. La so velocidá relativa neta ye d'unos 39 km/s.

El sistema estelar más cercanu a Gliese 687 ye Struve 2398, asitiáu a pocu más de 4 años lluz.^[14]
