58 Ophiuchi (58 Oph)^[8]^[9] ye una estrella na constelación d'Ophiuchus. Tien magnitú aparente +4,87 y alcuéntrase a 57 años lluz de distancia del Sistema Solar.

58 Ophiuchi ye una estrella blancu-mariella de la secuencia principal de tipu espectral F5V. Los dos componentes del sistema Diadem (α Comae Berenices), ι Pegasi A o ψ Capricorni son estrelles de carauterístiques asemeyaes a 58 Ophiuchi. Esta postrera tien una temperatura efectivo de 6356 - 6465 K, la cifra exauta varia según la fonte consultada.^[10]^[11] Xira sobre sigo mesma con una velocidá de rotación proyeutada de 12 km/s, lo que trai que'l so periodu de rotación ye inferior a 6,07 díes.^[10] Anque presenta un conteníu metálico inferior al del Sol, diversos estudios determinen valores pal so índiz de metalicidá [Fe/H] entendíos ente -0,16 y -0,31;^[12]^[11]^[13] un valor mediu de les distintes midíes supón que la so bayura relativa de fierro ye un 43% inferior a la solar.

58 Ophiuchi tien una masa de 1,19 mases solares y la so edá envalórase ente 1900 y 3500 millones d'años.^[12]^[13] Al igual que'l Sol y la mayor parte de les estrelles de la nuesa redolada, 58 Ophiuchi ye una estrella del discu finu.^[13]
