TYC 1422-614-1 b
TYC 1422-614-1 b is a cold gas giant orbiting TYC 1422-614-1 in the constellation Leo. It lies about 2,193 light-years from Earth and was discovered in 2014 using the radial velocity method.
Is TYC 1422-614-1 b in the Habitable Zone?
TYC 1422-614-1 b orbits inside the inner edge of the habitable zone of TYC 1422-614-1. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of TYC 1422-614-1: 3.739–9.112 AU (conservative: 4.736–8.639 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TYC 1422-614-1 b — one full orbit around TYC 1422-614-1 — lasts 198.4 Earth days, between the years of Mercury (88 days) and Earth (365 days). It orbits at an average distance of 0.690 AU — comparable to the inner Solar System. Its orbit is mildly elliptical (eccentricity 0.06).
How Was TYC 1422-614-1 b Discovered?
TYC 1422-614-1 b was discovered in 2014 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 TYC 1422-614-1 b?
TYC 1422-614-1 b is 2,193.1 light-years (672.4 parsecs) from Earth. Light arriving here tonight left the planet about 2,193 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 38,598,560 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. TYC 1422-614-1 b scores 0.09, ranking #4,525 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
