HD 17092 is a star in the constellation of Perseus. It has an orange hue but is visible only with binoculars or better equipment, having an apparent visual magnitude of 7.73.[2] The distance to this star is approximately 750 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +5.5 km/s.[5]
This object is an aging giant star with a stellar classification of K0III,[3] which means it has exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence.[4] It is roughly six billion years old with 1.2[6] times the mass of the Sun and has expanded to 12 times the Sun's radius.[1] The star is radiating 57[1] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,630 K.[6]
Planetary system
On 6 May 2007, a planet HD 17092 b was discovered with the Hobby-Eberly Telescope by Niedzielski who used the wobble method. This planet is a massive gas giant and orbits at 1.29 astronomical units from the star with a period of about 360 days.[4]
