HD 62364 c
The parameters of this planet are disputed or ambiguous in the scientific literature.
HD 62364 c is a exoplanet orbiting the F7 V star HD 62364 in the constellation Mensa. It lies about 173 light-years from Earth and was discovered in 2022 using the radial velocity method.
Is HD 62364 c in the Habitable Zone?
HD 62364 c orbits beyond the outer edge of the habitable zone of HD 62364. At that distance, any surface water would almost certainly be frozen.
Habitable zone of HD 62364: 1.200–2.797 AU (conservative: 1.520–2.652 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on HD 62364 c — one full orbit around HD 62364 — lasts 74,839.9 Earth days, longer than Jupiter's 12-year orbit. It orbits at an average distance of 36.984 AU. Its orbit is highly elliptical (eccentricity 0.77), swinging dramatically closer to and farther from its star.
How Was HD 62364 c Discovered?
HD 62364 c was discovered in 2022 using the radial velocity method, with observations from Multiple Observatories.
The radial velocity method measures the subtle wobble of a star caused by the gravitational pull of an orbiting planet, visible as periodic shifts in the star's light spectrum. The size of the wobble reveals the planet's minimum mass.
How Far Away Is HD 62364 c?
HD 62364 c is 173.2 light-years (53.1 parsecs) from Earth. Light arriving here tonight left the planet around the year 1853. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 3,048,320 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. HD 62364 c scores 0.08, ranking #4,738 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
