HD 173936 is a star in the northern constellation of Lyra. It has a blue-white hue and is just barely visible to the naked eye with an apparent visual magnitude of 6.06. [2] Based upon parallax measurements, the star is located at a distance of approximately 900 light years from the Sun, [1] and has an absolute magnitude of −1.14. [2] It is drifting closer with a radial velocity of −19 km/s. [2]
This object is a B-type main-sequence star with a stellar classification of B6 V. [4] It is around 22.4 [7] million years old with 4.6 [3] times the mass of the Sun and has a high rate of spin, showing a projected rotational velocity of 116 km/s. [6] It is radiating 701 [3] times the luminosity of the Sun from its photosphere at an effective temperature of 13,932 K. [3]
