58 Ophiuchi is a single[10] star in the equatorial constellation of Ophiuchus. It is visible to the naked eye as a faint, yellow-white hued star with an apparent visual magnitude of 4.86.[2] This object is approximately 57.6 light years away based on parallax,[1] and is drifting further from the Earth with a heliocentric radial velocity of +10 km/s.[5]

This is an ordinary F-type main-sequence star with a stellar classification of F5V.[3] It is 2.7[7] billion years old with a projected rotational velocity of 12 km/s.[8] The star has an estimated 1.26 times the mass of the Sun and 1.3 times the Sun's radius.[6] It is radiating three[2] times the luminosity of the Sun from its photosphere at an effective temperature of 6,447 K.[7]
