Kepler-607 c
Kepler-607 c is a mini-Neptune orbiting Kepler-607 in the constellation Cygnus. It lies about 1,693 light-years from Earth and was discovered in 2021 using the transit method.
How Big Is Kepler-607 c?
Kepler-607 c has a radius of 2.76 times that of Earth.
Is Kepler-607 c in the Habitable Zone?
The position of Kepler-607 c relative to the habitable zone of Kepler-607 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-607: 0.502–1.204 AU (conservative: 0.636–1.142 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-607 c — one full orbit around Kepler-607 — lasts 39.7 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-607 c Discovered?
Kepler-607 c was discovered in 2021 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-607 c?
Kepler-607 c is 1,693.1 light-years (519.1 parsecs) from Earth. Light arriving here tonight left the planet about 1,693 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 29,798,560 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. Kepler-607 c scores 0.34, ranking #832 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
