Kepler-341 c
Kepler-341 c is a super-Earth orbiting Kepler-341 in the constellation Lyra. It lies about 3,415 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is Kepler-341 c?
Kepler-341 c has a radius of 1.70 times that of Earth.
Is Kepler-341 c in the Habitable Zone?
Kepler-341 c orbits inside the inner edge of the habitable zone of Kepler-341. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of Kepler-341: 0.820–1.921 AU (conservative: 1.039–1.822 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-341 c — one full orbit around Kepler-341 — lasts 8.01 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.080 AU — closer to its star than Mercury is to the Sun.
How Was Kepler-341 c Discovered?
Kepler-341 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-341 c?
Kepler-341 c is 3,415.0 light-years (1,047.0 parsecs) from Earth. Light arriving here tonight left the planet about 3,415 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 60,104,000 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-341 c scores 0.28, ranking #2,390 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-341 c
Is Kepler-341 c habitable?
No — Kepler-341 c orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is Kepler-341 c?
Kepler-341 c is about 3,415 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 60,104,000 years to get there.
How big is Kepler-341 c compared to Earth?
Kepler-341 c has 1.70 times the radius of Earth.
How long is a year on Kepler-341 c?
One orbit around Kepler-341 takes 8.0 Earth days — short enough that 46 of its years would fit into one Earth year.
