KOI-7368 b
KOI-7368 b is a mini-Neptune orbiting KOI-7368 in the constellation Cygnus. It lies about 864 light-years from Earth and was discovered in 2022 using the transit method.
How Big Is KOI-7368 b?
KOI-7368 b has a radius of 2.22 times that of Earth.
Is KOI-7368 b in the Habitable Zone?
The position of KOI-7368 b relative to the habitable zone of KOI-7368 cannot be precisely determined from the available orbital data.
Habitable zone of KOI-7368: 0.556–1.333 AU (conservative: 0.705–1.264 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on KOI-7368 b — one full orbit around KOI-7368 — lasts 6.84 Earth days, shorter than Mercury's 88-day year.
How Was KOI-7368 b Discovered?
KOI-7368 b was discovered in 2022 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 KOI-7368 b?
KOI-7368 b is 864.3 light-years (265.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1162. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 15,211,680 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. KOI-7368 b scores 0.26, ranking #2,965 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About KOI-7368 b
Is KOI-7368 b habitable?
KOI-7368 b is not known to orbit within the habitable zone of KOI-7368, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is KOI-7368 b?
KOI-7368 b is about 864 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 15,211,680 years to get there.
How big is KOI-7368 b compared to Earth?
KOI-7368 b has 2.22 times the radius of Earth.
How long is a year on KOI-7368 b?
One orbit around KOI-7368 takes 6.8 Earth days — short enough that 53 of its years would fit into one Earth year.
