KIC 3558849 b
KIC 3558849 b is a cold gas giant orbiting KIC 3558849 in the constellation Cygnus. It lies about 3,965 light-years from Earth and was discovered in 2015 using the transit method.
How Big Is KIC 3558849 b?
KIC 3558849 b has a radius of 6.90 times that of Earth, or 0.62 times the radius of Jupiter.
Is KIC 3558849 b in the Habitable Zone?
The position of KIC 3558849 b relative to the habitable zone of KIC 3558849 cannot be precisely determined from the available orbital data.
Habitable zone of KIC 3558849: 0.845–1.973 AU (conservative: 1.070–1.870 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on KIC 3558849 b — one full orbit around KIC 3558849 — lasts 1,322.3 Earth days, longer than an Earth year.
How Was KIC 3558849 b Discovered?
KIC 3558849 b was discovered in 2015 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 KIC 3558849 b?
KIC 3558849 b is 3,965.1 light-years (1,215.7 parsecs) from Earth. Light arriving here tonight left the planet about 3,965 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 69,785,760 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. KIC 3558849 b scores 0.41, ranking #431 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
