HD 171301 is a suspected binary star^[11] system in the northern constellation of Lyra. It has not been well-studied.^[5] The brighter member of the pair, designated component A,^[3] has a blue-white hue and is visible to the naked eye with an apparent visual magnitude of 5.47.^[2] The system is located at a distance of approximately 347 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −10 km/s.^[6]

The stellar classification of HD 171301 is B8IV,^[4] matching a late B-type star that may be a subgiant that is evolving off the main sequence. HD 171301 appears to be a type of chemically peculiar mercury-manganese star.^[5] It has an estimated mass three^[7] times that of the Sun and 2.7 times the Sun's radius.^[8] The star is spinning with a projected rotational velocity of 36 km/s.^[5] It is radiating 124^[7] times the luminosity of the Sun from its photosphere at an effective temperature of 11,695 K.^[7]

Its companion, component B, is a 13th magnitude star of an unknown spectral type.^[12] It was first reported by S. W. Burnham in 1891. As of 1998, it was located at an angular separation of 6.7 arcseconds from the brighter star along a position angle of 157°.^[3]
