HD 110014 b
HD 110014 b is a cold gas giant orbiting the K2 III star HD 110014 in the constellation Virgo. It lies about 329 light-years from Earth and was discovered in 2009 using the radial velocity method.
Is HD 110014 b in the Habitable Zone?
HD 110014 b orbits inside the inner edge of the habitable zone of HD 110014. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of HD 110014: 9.910–24.547 AU (conservative: 12.553–23.272 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on HD 110014 b — one full orbit around HD 110014 — lasts 835.5 Earth days, longer than an Earth year. It orbits at an average distance of 2.140 AU. Its orbit is highly elliptical (eccentricity 0.46), swinging dramatically closer to and farther from its star.
How Was HD 110014 b Discovered?
HD 110014 b was discovered in 2009 using the radial velocity method, with observations from La Silla 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 110014 b?
HD 110014 b is 328.6 light-years (100.8 parsecs) from Earth. Light arriving here tonight left the planet around the year 1698. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 5,783,360 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. HD 110014 b scores 0.09, ranking #4,497 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
