Kepler-560 b
Kepler-560 b is a super-Earth orbiting Kepler-560 in the constellation Cygnus. It lies about 357 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-560 b?
Kepler-560 b has a radius of 1.72 times that of Earth.
Is Kepler-560 b in the Habitable Zone?
The position of Kepler-560 b relative to the habitable zone of Kepler-560 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-560: 0.102–0.264 AU (conservative: 0.129–0.251 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-560 b — one full orbit around Kepler-560 — lasts 18.5 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-560 b Discovered?
Kepler-560 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-560 b?
Kepler-560 b is 356.5 light-years (109.3 parsecs) from Earth. Light arriving here tonight left the planet around the year 1670. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 6,274,400 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-560 b scores 0.65, ranking #93 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-560 b
Is Kepler-560 b habitable?
Kepler-560 b is not known to orbit within the habitable zone of Kepler-560, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-560 b?
Kepler-560 b is about 357 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 6,274,400 years to get there.
How big is Kepler-560 b compared to Earth?
Kepler-560 b has 1.72 times the radius of Earth.
How long is a year on Kepler-560 b?
One orbit around Kepler-560 takes 18.5 Earth days — short enough that 20 of its years would fit into one Earth year.
