HD 62364 c
The parameters of this planet are disputed or ambiguous in the scientific literature.
HD 62364 c is a exoplanet orbiting 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?
The position of HD 62364 c relative to the habitable zone of HD 62364 cannot be precisely determined from the available orbital data.
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 #4,735 of 5,565 planets with a known ESI. For reference, Mars scores about 0.70.
