Kepler-132 c
Kepler-132 c is a super-Earth orbiting Kepler-132 in the constellation Lyra. It lies about 1,140 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is Kepler-132 c?
Kepler-132 c has a radius of 1.28 times that of Earth.
Is Kepler-132 c in the Habitable Zone?
Kepler-132 c orbits inside the inner edge of the habitable zone of Kepler-132. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of Kepler-132: 0.941–2.205 AU (conservative: 1.192–2.091 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-132 c — one full orbit around Kepler-132 — lasts 6.41 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.068 AU — closer to its star than Mercury is to the Sun.
How Was Kepler-132 c Discovered?
Kepler-132 c was discovered in 2014 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-132 c?
Kepler-132 c is 1,140.1 light-years (349.5 parsecs) from Earth. Light arriving here tonight left the planet about 1,140 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 20,065,760 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-132 c scores 0.29, ranking #1,760 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-132 c
Is Kepler-132 c habitable?
No — Kepler-132 c orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is Kepler-132 c?
Kepler-132 c is about 1,140 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 20,065,760 years to get there.
How big is Kepler-132 c compared to Earth?
Kepler-132 c has 1.28 times the radius of Earth.
How long is a year on Kepler-132 c?
One orbit around Kepler-132 takes 6.4 Earth days — short enough that 57 of its years would fit into one Earth year.
