15 Leonis Minoris (15 LMi) ye una estrella de magnitú aparente +5,10^[8] que s'atopa a 60 años lluz de distancia del Sistema Solar. Magar la so denominación de Flamsteed, ta encuadrada dientro de la constelación del sietestrellu.

15 Leonis Minoris ye una nana mariella de tipu espectral G0.5Va^[8] con una temperatura efectivo de 5958 K.^[9] La so lluminosidá ye 2,6 vegaes mayor que la lluminosidá solar —un 60% superior a la que cabría esperar pol so tipu espectral—^[10] y tien un radiu ente un 47% y un 57% más grande que'l del Sol,^[11] parámetros que suxeren que 15 Leonis Minoris ye una estrella más evolucionada que'l Sol. La so masa averada ye de 1,17 ± 0,4 mases solares y puede tener una edá envalorada a partir d'isocrones— de 4500 ± 400 millones d'años.^[12] Xira sobre sigo mesma con una velocidá de rotación proyeutada de 3 km/s^[12] y nun presenta actividá cromosférica.^[13] Nun se detectó escesu nel infrarroxu nin a 24 μm nin a 70 μm,^[14] lo qu'en principiu refuga la presencia d'un discu de polvu al so alredor.

15 Leonis Minoris presenta una metalicidá —bayura relativa d'elementos más pesaos que l'heliu— daqué mayor que la solar ([Fe/H] = +0,15). Otros dolce elementos evaluaos amuesen el mesmu enclín, siendo los sos niveles cimeros a los del Sol en tolos casos; l'escandiu ye l'elementu más «sobreabundante», siendo la so bayura relativa casi'l doble que nel Sol.^[9] Igualmente la rellación oxíxenu/hidróxenu ye aproximao un 70% más elevada que na nuesa estrella.^[15]
