WASP-107 c
WASP-107 c is a cold gas giant orbiting WASP-107 in the constellation Virgo. It lies about 211 light-years from Earth and was discovered in 2020 using the radial velocity method.
Is WASP-107 c in the Habitable Zone?
The position of WASP-107 c relative to the habitable zone of WASP-107 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on WASP-107 c — one full orbit around WASP-107 — lasts 1,066.0 Earth days, longer than an Earth year. Its orbit is mildly elliptical (eccentricity 0.27).
How Was WASP-107 c Discovered?
WASP-107 c was discovered in 2020 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 WASP-107 c?
WASP-107 c is 211.2 light-years (64.7 parsecs) from Earth. Light arriving here tonight left the planet around the year 1815. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 3,717,120 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. WASP-107 c scores 0.11, ranking #4,376 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
