KIC 7917485 b
KIC 7917485 b is a cold gas giant orbiting the A star KIC 7917485 in the constellation Cygnus. It lies about 4,510 light-years from Earth and was discovered in 2016 using the pulsation timing variations method.
Is KIC 7917485 b in the Habitable Zone?
The position of KIC 7917485 b relative to the habitable zone of KIC 7917485 cannot be precisely determined from the available orbital data.
Habitable zone of KIC 7917485: 2.194–5.062 AU (conservative: 2.779–4.799 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on KIC 7917485 b — one full orbit around KIC 7917485 — lasts 840.0 Earth days, longer than an Earth year. Its orbit is mildly elliptical (eccentricity 0.15).
How Was KIC 7917485 b Discovered?
KIC 7917485 b was discovered in 2016 using the pulsation timing variations method, with observations from Kepler.
Pulsation timing variations find planets around stars that pulsate with stable rhythms; an orbiting planet periodically delays or advances the arrival of these pulsations.
How Far Away Is KIC 7917485 b?
KIC 7917485 b is 4,510.4 light-years (1,382.9 parsecs) from Earth. Light arriving here tonight left the planet about 4,510 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 79,383,040 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 7917485 b scores 0.33, ranking #911 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
