Kepler-610 c
Kepler-610 c is a sub-Neptune orbiting Kepler-610 in the constellation Cygnus. It lies about 2,759 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-610 c?
Kepler-610 c has a radius of 3.30 times that of Earth.
Is Kepler-610 c in the Habitable Zone?
The position of Kepler-610 c relative to the habitable zone of Kepler-610 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-610: 0.888–2.084 AU (conservative: 1.125–1.976 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-610 c — one full orbit around Kepler-610 — lasts 151.9 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-610 c Discovered?
Kepler-610 c was discovered in 2016 using the transit method, with observations from Kepler.
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is Kepler-610 c?
Kepler-610 c is 2,758.7 light-years (845.8 parsecs) from Earth. Light arriving here tonight left the planet about 2,759 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 48,553,120 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. Kepler-610 c scores 0.52, ranking #236 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-610 c
Is Kepler-610 c habitable?
Kepler-610 c is not known to orbit within the habitable zone of Kepler-610, and as a sub-Neptune it is an unlikely candidate for life as we know it.
How far away is Kepler-610 c?
Kepler-610 c is about 2,759 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 48,553,120 years to get there.
How big is Kepler-610 c compared to Earth?
Kepler-610 c has 3.30 times the radius of Earth.
How long is a year on Kepler-610 c?
One orbit around Kepler-610 takes 151.9 Earth days.
