Kepler-524 b
Kepler-524 b is a super-Earth orbiting Kepler-524 in the constellation Cygnus. It lies about 3,452 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-524 b?
Kepler-524 b has a radius of 1.91 times that of Earth.
Is Kepler-524 b in the Habitable Zone?
The position of Kepler-524 b relative to the habitable zone of Kepler-524 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-524: 0.882–2.065 AU (conservative: 1.117–1.958 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-524 b — one full orbit around Kepler-524 — lasts 7.97 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-524 b Discovered?
Kepler-524 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-524 b?
Kepler-524 b is 3,451.5 light-years (1,058.2 parsecs) from Earth. Light arriving here tonight left the planet about 3,452 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 60,746,400 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-524 b scores 0.26, ranking #2,808 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-524 b
Is Kepler-524 b habitable?
Kepler-524 b is not known to orbit within the habitable zone of Kepler-524, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-524 b?
Kepler-524 b is about 3,452 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 60,746,400 years to get there.
How big is Kepler-524 b compared to Earth?
Kepler-524 b has 1.91 times the radius of Earth.
How long is a year on Kepler-524 b?
One orbit around Kepler-524 takes 8.0 Earth days — short enough that 46 of its years would fit into one Earth year.
