Kepler-595 c
Kepler-595 c is a terrestrial planet orbiting Kepler-595 in the constellation Cygnus. It lies about 2,097 light-years from Earth and was discovered in 2020 using the transit method.
How Big Is Kepler-595 c?
Kepler-595 c has a radius of 1.01 times that of Earth. Its mass is 3.3 times that of Earth.
Is Kepler-595 c in the Habitable Zone?
The position of Kepler-595 c relative to the habitable zone of Kepler-595 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-595 c — one full orbit around Kepler-595 — lasts 12.4 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-595 c Discovered?
Kepler-595 c was discovered in 2020 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-595 c?
Kepler-595 c is 2,097.2 light-years (643.0 parsecs) from Earth. Light arriving here tonight left the planet about 2,097 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 36,910,720 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-595 c scores 0.32, ranking #990 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-595 c
Is Kepler-595 c habitable?
Kepler-595 c is not known to orbit within the habitable zone of Kepler-595, and as a terrestrial planet it is an unlikely candidate for life as we know it.
How far away is Kepler-595 c?
Kepler-595 c is about 2,097 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 36,910,720 years to get there.
How big is Kepler-595 c compared to Earth?
Kepler-595 c has 1.01 times the radius of Earth and about 3.3 times its mass.
How long is a year on Kepler-595 c?
One orbit around Kepler-595 takes 12.4 Earth days — short enough that 29 of its years would fit into one Earth year.
