HR 4699 is a single [11] star in the southern constellation of Corvus. It is orange in hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.14. [2] This star is located at a distance of approximately 201 light years from the Sun based on parallax. [1] It is drifting further away with a radial velocity of +14 km/s, after come to within 45.1 light-years some four million years ago. [2]
This is an aging giant star with a stellar classification of K0 III, [3] having exhausted the supply of hydrogen at its core then cooled and expanded to almost ten [6] times the Sun's radius. It is nearly two [5] billion years old with 1.76 times the mass of the Sun. [5] The star is radiating 43 times the luminosity of the Sun from its photosphere at an effective temperature of 4,707 K.
