TOI-1634 c
TOI-1634 c is a exoplanet orbiting the M2 star TOI-1634 in the constellation Perseus. It lies about 115 light-years from Earth and was discovered in 2022 using the radial velocity method.
Is TOI-1634 c in the Habitable Zone?
The position of TOI-1634 c relative to the habitable zone of TOI-1634 cannot be precisely determined from the available orbital data.
Habitable zone of TOI-1634: 0.139–0.360 AU (conservative: 0.176–0.341 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on TOI-1634 c — one full orbit around TOI-1634 — lasts 103.0 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was TOI-1634 c Discovered?
TOI-1634 c was discovered in 2022 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 TOI-1634 c?
TOI-1634 c is 115.0 light-years (35.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1911. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 2,024,000 years to make the journey.
