30 Lyncis (30 Lyn / HD 69548 / HR 3254)^[6] ye una estrella asitiada na constelación del Llobu cerval. La so magnitú aparente ye +5,89 y alcuéntrase a 103 años lluz del Sistema Solar.

Coordenaes: 8^h 20^m 26.06^s, 57^° 44^′ 35.806^″

30 Lyncis ye una estrella blancu-mariella de la secuencia principal de tipu espectral F4V con una temperatura superficial de 6709 K.^[7] El so radiu ye un 42% más grande que'l radiu solar^[8] y rota con una velocidá de siquier 53,9 km/s.^[7] Les estrelles de la secuencia principal de menor masa y temperatura xiren sobre sigo mesmes amodo —la velocidá de rotación del Sol ye de 2 km/s—, ente que dicha velocidá aumenta cola masa (vease rotación estelar). La división ente dambos tipos de rotores ye relativamente sópita, tando dichu puntu d'inflexón asitiáu na metá de la clase F.^[9] 30 Lyncis, con una velocidá de rotación proyeutada 27 vegaes más alta que'l Sol, asítiase xusto percima de dichu llende, siendo'l so periodu de rotación igual o inferior a 1,27 díes.^[10] Coles mesmes, presenta una metalicidá (bayura relativa d'elementos más pesaos que l'heliu) per debaxo de la del Sol ([Fe/H] = -0,09). La so edá envalórase en 1500 millones d'años.^[11] Al igual que'l Sol, ye una estrella solitaria que nun forma parte d'un sistema estelar.^[12]
