HR 7722 c is an exoplanet orbiting the star HR 7722.[1] It is a Neptune-sized planet and was discovered on 17 August 2011 by the HARPS program.

The planet has a mass of ≥24 ± 5 Earth masses and orbits its parent star at a semimajor axis of 1.18 ± 0.025 AU, an eccentricity of 0.32 ± 0.11, and in 525.8 ± 9.2 days. Its orbital path lies mainly outside HR 7722's habitable zone, meaning it is too cold to support life, but due to its elliptical orbit, but it passes into the habitable zone briefly each orbit.
