KIC 5437945 b
KIC 5437945 b is a cold gas giant orbiting KIC 5437945 in the constellation Lyra. It lies about 4,155 light-years from Earth and was discovered in 2015 using the transit method.
How Big Is KIC 5437945 b?
KIC 5437945 b has a radius of 6.40 times that of Earth, or 0.57 times the radius of Jupiter.
Is KIC 5437945 b in the Habitable Zone?
The position of KIC 5437945 b relative to the habitable zone of KIC 5437945 cannot be precisely determined from the available orbital data.
Habitable zone of KIC 5437945: 1.083–2.520 AU (conservative: 1.372–2.389 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on KIC 5437945 b — one full orbit around KIC 5437945 — lasts 440.8 Earth days, longer than an Earth year.
How Was KIC 5437945 b Discovered?
KIC 5437945 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 5437945 b?
KIC 5437945 b is 4,155.3 light-years (1,274.0 parsecs) from Earth. Light arriving here tonight left the planet about 4,155 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 73,133,280 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 5437945 b scores 0.36, ranking #710 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
