Distante 104 años lluz del Sistema Solar, les carauterístiques físiques de 24 Leonis Minoris faen d'esta estrella una análoga solar, esto ye, una estrella bien asemeyada al Sol en munchos aspeutos. De tipu espectral G0V,^[9] tien una temperatura efectivo de 5787 ± 32 K.^[10] Relluma con una lluminosidá 2,34 vegaes mayor que la lluminosidá solar^[11] y el so diámetru ye un 46% más grande que'l de la nuesa estrella.^[12] La so velocidá de rotación proyeutada ye de 1 km/s.^[13] Con una masa aproximao un 7% mayor que la masa solar, ye una estrella más antigua y evolucionada que'l Sol; tien una edá envalorada nel rangu de 6500 - 8000 millones d'años, la cifra exauta varia según la fonte consultada.^[12]^[13] Al igual que'l Sol, ye una estrella del discu finu.^[14]

24 Leonis Minoris tien un conteníu relativo de fierro comparable al del Sol ([Fe/H] = +0,05). Diversos elementos evaluaos presenten valores asemeyaos a les solares. Cabo señalar l'escandiu, daqué más abondosu y, nel otru estremu, l'azufre, que'l so conteníu ye un 33% menor que na nuesa estrella.^[11]
