KIC 5479689 b
KIC 5479689 b is a hot Jupiter orbiting KIC 5479689 in the constellation Cygnus. It lies about 1,484 light-years from Earth and was discovered in 2021 using the orbital brightness modulation method.
Is KIC 5479689 b in the Habitable Zone?
The position of KIC 5479689 b relative to the habitable zone of KIC 5479689 cannot be precisely determined from the available orbital data.
Habitable zone of KIC 5479689: 0.610–1.451 AU (conservative: 0.773–1.376 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on KIC 5479689 b — one full orbit around KIC 5479689 — lasts just 40.8 hours, shorter than Mercury's 88-day year.
How Was KIC 5479689 b Discovered?
KIC 5479689 b was discovered in 2021 using the orbital brightness modulation method, with observations from Kepler.
Orbital brightness modulation detects a planet from minute periodic changes in the combined light of the system as the planet orbits — including light reflected by the planet and relativistic effects it induces on the star.
How Far Away Is KIC 5479689 b?
KIC 5479689 b is 1,483.8 light-years (455.0 parsecs) from Earth. Light arriving here tonight left the planet about 1,484 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 26,114,880 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 5479689 b scores 0.06, ranking #5,061 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About KIC 5479689 b
Is KIC 5479689 b habitable?
KIC 5479689 b is not known to orbit within the habitable zone of KIC 5479689, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is KIC 5479689 b?
KIC 5479689 b is about 1,484 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 26,114,880 years to get there.
How long is a year on KIC 5479689 b?
One orbit around KIC 5479689 takes 1.7 Earth days — short enough that 215 of its years would fit into one Earth year.
