Kepler-613 b
Kepler-613 b is a mini-Neptune orbiting Kepler-613 in the constellation Lyra. It lies about 2,810 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-613 b?
Kepler-613 b has a radius of 2.29 times that of Earth.
Is Kepler-613 b in the Habitable Zone?
The position of Kepler-613 b relative to the habitable zone of Kepler-613 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-613: 0.709–1.673 AU (conservative: 0.898–1.586 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-613 b — one full orbit around Kepler-613 — lasts 15.8 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-613 b Discovered?
Kepler-613 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-613 b?
Kepler-613 b is 2,809.8 light-years (861.5 parsecs) from Earth. Light arriving here tonight left the planet about 2,810 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 49,452,480 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-613 b scores 0.26, ranking #2,795 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-613 b
Is Kepler-613 b habitable?
Kepler-613 b is not known to orbit within the habitable zone of Kepler-613, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is Kepler-613 b?
Kepler-613 b is about 2,810 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 49,452,480 years to get there.
How big is Kepler-613 b compared to Earth?
Kepler-613 b has 2.29 times the radius of Earth.
How long is a year on Kepler-613 b?
One orbit around Kepler-613 takes 15.8 Earth days — short enough that 23 of its years would fit into one Earth year.
