CoRoT-20 c
CoRoT-20 c is a exoplanet orbiting CoRoT-20 in the constellation Monoceros. It lies about 2,753 light-years from Earth and was discovered in 2018 using the radial velocity method.
Is CoRoT-20 c in the Habitable Zone?
The position of CoRoT-20 c relative to the habitable zone of CoRoT-20 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on CoRoT-20 c — one full orbit around CoRoT-20 — lasts 1,675.0 Earth days, longer than an Earth year. It orbits at an average distance of 2.900 AU. Its orbit is highly elliptical (eccentricity 0.60), swinging dramatically closer to and farther from its star.
How Was CoRoT-20 c Discovered?
CoRoT-20 c was discovered in 2018 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 CoRoT-20 c?
CoRoT-20 c is 2,753.0 light-years (844.1 parsecs) from Earth. Light arriving here tonight left the planet about 2,753 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 48,452,800 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. CoRoT-20 c scores 0.20, ranking #3,833 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
