HIP 14810 c
HIP 14810 c is a cold gas giant orbiting the G5 star HIP 14810 in the constellation Aries. It lies about 165 light-years from Earth and was discovered in 2006 using the radial velocity method.
Is HIP 14810 c in the Habitable Zone?
HIP 14810 c orbits inside the inner edge of the habitable zone of HIP 14810. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of HIP 14810: 0.752–1.784 AU (conservative: 0.953–1.691 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on HIP 14810 c — one full orbit around HIP 14810 — lasts 147.7 Earth days, between the years of Mercury (88 days) and Earth (365 days). It orbits at an average distance of 0.549 AU — comparable to the inner Solar System. Its orbit is mildly elliptical (eccentricity 0.16).
How Was HIP 14810 c Discovered?
HIP 14810 c was discovered in 2006 using the radial velocity method, with observations from W. M. Keck 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 HIP 14810 c?
HIP 14810 c is 164.6 light-years (50.5 parsecs) from Earth. Light arriving here tonight left the planet around the year 1862. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 2,896,960 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 14810 c scores 0.28, ranking #2,156 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About HIP 14810 c
Is HIP 14810 c habitable?
No — HIP 14810 c orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is HIP 14810 c?
HIP 14810 c is about 165 light-years from Earth in the constellation Aries. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 2,896,960 years to get there.
How long is a year on HIP 14810 c?
One orbit around HIP 14810 takes 147.7 Earth days.
