HD 60292 b
HD 60292 b is a cold gas giant orbiting the K0 III star HD 60292 in the constellation Camelopardalis. It lies about 1,028 light-years from Earth and was discovered in 2020 using the radial velocity method.
Is HD 60292 b in the Habitable Zone?
HD 60292 b orbits inside the inner edge of the habitable zone of HD 60292. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of HD 60292: 12.652–31.481 AU (conservative: 16.025–29.847 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on HD 60292 b — one full orbit around HD 60292 — lasts 495.4 Earth days, longer than an Earth year. It orbits at an average distance of 1.500 AU. Its orbit is mildly elliptical (eccentricity 0.27).
How Was HD 60292 b Discovered?
HD 60292 b was discovered in 2020 using the radial velocity method, with observations from Bohyunsan Optical Astronomical Observatory.
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 60292 b?
HD 60292 b is 1,028.1 light-years (315.2 parsecs) from Earth. Light arriving here tonight left the planet about 1,028 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 18,094,560 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 60292 b scores 0.08, ranking #4,679 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
