Delta Leporis (δ Lep / 15 Leporis / HD 39364 / HR 2035)^[7] ye una estrella na constelación de Lepus. De magnitú aparente +3,81, alcuéntrase a una distancia de 112 años lluz respectu al Sistema Solar.

Delta Leporis ye una subxigante de tipu espectral K1IV^[7] —catalogada tamién como G8III/IV— con una temperatura efectivo de cerca de 4600 K.^[8] 46 vegaes más lluminosa que'l Sol, tien un radiu cuasi 10 vegaes más grande que'l radiu solar, cifra llograda a partir del valor del so diámetru angular —2,63 milisegundos d'arcu—.^[9] A pesar del so tamañu, ye menos masiva que'l Sol, con una masa de 0,94 mases solares. Ye una estrella evolucionada con una edá de 10.700 millones d'años.^[8]

La metalicidá de Delta Leporis ye notablemente inferior a la del Sol ([M/H] = -0,64), con una bayura relativa de fierro en redol al 20% de la esistente na nuesa estrella. Los niveles d'otros elementos como magnesiu, aluminiu, siliciu y calciu nun son tan baxos como'l de fierro pero son menores que los niveles solares.^[10] A diferencia del Sol y la mayoría de les estrelles de la nuesa redolada, estrelles del discu finu, Delta Leporis ye una estrella del discu gruesu.^[11]
