HD 167257 (HR 6821) is a solitary star in the southern constellation Telescopium. It has an apparent magnitude of 6.05, making it faintly visible to the naked eye. Parallax measurements place the star at a distance of 420 light years and has a radial velocity of −5.1 km/s, which is poorly constrained. This indicates that it is drifting towards the Solar System.

rdfs:comment	HD 167257 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Kikaren. Den har en skenbar magnitud av ca 6,06 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 8,2 mas, beräknas den befinna sig på ett avstånd på ca 400 ljusår (ca 122 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -5 km/s.

has abstract	HD 167257 (HR 6821) is a solitary star in the southern constellation Telescopium. It has an apparent magnitude of 6.05, making it faintly visible to the naked eye. Parallax measurements place the star at a distance of 420 light years and has a radial velocity of −5.1 km/s, which is poorly constrained. This indicates that it is drifting towards the Solar System. HD 167257 has a stellar classification of B9 V, indicating that it is an ordinary B-type main-sequence star. It has 2.63 times the mass of the Sun, and 2.8 times the radius of the Sun. It shines with a luminosity of about 65 L☉ from its photosphere at an effective temperature of 10,139 K, giving it a bluish white hue. HD 167257 is estimated to be about 240 million years old – 58.6% through its main sequence lifetime – and spins modestly with a projected rotational velocity of 61 km/s; it has a solar metallicity.
