HD 192310 b is an exoplanet orbiting the star HD 192310 (HR 7722). [1] It orbits its parent star with a semimajor axis of 0.32 ± 0.005 AU, an eccentricity of 0.13 ± 0.04. and an orbital period of 74.72 days. [2]
The Neptune-sized planet has at least 21 times the mass of Earth [3] and 3 to 4 times its diameter.
HD 192310 b was discovered on 1 November 2010 and lies within the inner edge of the habitable zone of HD 192310.
