It appears as a sixth magnitude star, near the lower limit of visibility to the naked eye, having an apparent visual magnitude of 5.89. The system is located 658 light years away, as determined from its annual parallax shift of 4.95 mas. It is moving closer to the Earth with a heliocentric radial velocity of –22 km/s. This is a single-lined spectroscopic binary with an orbital period of 61.5 days and an eccentricity of 0.49. The visible component is a chemically peculiar mercury-manganese star with a stellar classification of B9p HgMn. It is narrow-lined with a projected rotational velocity of 7 km/s. The star is radiating 292 times the Sun's luminosity from its photosphere at an effective temperature of 13,200 K. John Flamsteed labelled this star as y Sagittae, but the designation was dropped by later authors and is now largely unknown.
