HIP 35965 b
HIP 35965 b is a cold gas giant orbiting HIP 35965 in the constellation Carina. It lies about 164 light-years from Earth and was discovered in 2022 using the radial velocity method.
Is HIP 35965 b in the Habitable Zone?
The position of HIP 35965 b relative to the habitable zone of HIP 35965 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on HIP 35965 b — one full orbit around HIP 35965 — lasts 26,125.6 Earth days, longer than Jupiter's 12-year orbit. It orbits at an average distance of 15.898 AU. Its orbit is mildly elliptical (eccentricity 0.14).
How Was HIP 35965 b Discovered?
HIP 35965 b 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 HIP 35965 b?
HIP 35965 b is 163.6 light-years (50.2 parsecs) from Earth. Light arriving here tonight left the planet around the year 1863. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 2,879,360 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. HIP 35965 b scores 0.07, ranking #4,896 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
