Kepler-696 b
Kepler-696 b is a hot Jupiter orbiting Kepler-696 in the constellation Cygnus. It lies about 4,620 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-696 b?
Kepler-696 b has a radius of 6.14 times that of Earth, or 0.55 times the radius of Jupiter.
Is Kepler-696 b in the Habitable Zone?
The position of Kepler-696 b relative to the habitable zone of Kepler-696 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-696: 0.840–1.972 AU (conservative: 1.063–1.869 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-696 b — one full orbit around Kepler-696 — lasts 4.19 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-696 b Discovered?
Kepler-696 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-696 b?
Kepler-696 b is 4,619.8 light-years (1,416.4 parsecs) from Earth. Light arriving here tonight left the planet about 4,620 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 81,308,480 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-696 b scores 0.13, ranking #4,283 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-696 b
Is Kepler-696 b habitable?
Kepler-696 b is not known to orbit within the habitable zone of Kepler-696, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is Kepler-696 b?
Kepler-696 b is about 4,620 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 81,308,480 years to get there.
How big is Kepler-696 b compared to Earth?
Kepler-696 b has 6.14 times the radius of Earth.
How long is a year on Kepler-696 b?
One orbit around Kepler-696 takes 4.2 Earth days — short enough that 87 of its years would fit into one Earth year.
