Kepler-1341 b
Kepler-1341 b is a mini-Neptune orbiting Kepler-1341 in the constellation Lyra. It lies about 1,556 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-1341 b?
Kepler-1341 b has a radius of 2.99 times that of Earth.
Is Kepler-1341 b in the Habitable Zone?
The position of Kepler-1341 b relative to the habitable zone of Kepler-1341 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1341: 0.373–0.914 AU (conservative: 0.472–0.866 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1341 b — one full orbit around Kepler-1341 — lasts 133.0 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-1341 b Discovered?
Kepler-1341 b 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-1341 b?
Kepler-1341 b is 1,555.6 light-years (477.0 parsecs) from Earth. Light arriving here tonight left the planet about 1,556 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 27,378,560 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-1341 b scores 0.64, ranking #103 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
