HD 196067 b
HD 196067 b is a cold gas giant orbiting the G0 V star HD 196067 in the constellation Octans. It lies about 130 light-years from Earth and was discovered in 2012 using the radial velocity method.
Is HD 196067 b in the Habitable Zone?
HD 196067 b orbits beyond the outer edge of the habitable zone of HD 196067. At that distance, any surface water would almost certainly be frozen.
Habitable zone of HD 196067: 1.387–3.245 AU (conservative: 1.757–3.076 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on HD 196067 b — one full orbit around HD 196067 — lasts 3,413.7 Earth days, longer than an Earth year. It orbits at an average distance of 4.710 AU. Its orbit is highly elliptical (eccentricity 0.56), swinging dramatically closer to and farther from its star.
How Was HD 196067 b Discovered?
HD 196067 b was discovered in 2012 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 196067 b?
HD 196067 b is 130.2 light-years (39.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1896. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 2,291,520 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 196067 b scores 0.23, ranking #3,428 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
