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 $$, 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 $$ 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 $2.63$; it has a solar metallicity.
