Kepler-292 e
Kepler-292 e is a mini-Neptune orbiting Kepler-292 in the constellation Cygnus. It lies about 3,446 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is Kepler-292 e?
Kepler-292 e has a radius of 2.67 times that of Earth.
Is Kepler-292 e in the Habitable Zone?
Kepler-292 e orbits inside the inner edge of the habitable zone of Kepler-292. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of Kepler-292: 0.536–1.281 AU (conservative: 0.679–1.215 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-292 e — one full orbit around Kepler-292 — lasts 12.0 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.097 AU — closer to its star than Mercury is to the Sun.
How Was Kepler-292 e Discovered?
Kepler-292 e was discovered in 2014 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-292 e?
Kepler-292 e is 3,445.8 light-years (1,056.5 parsecs) from Earth. Light arriving here tonight left the planet about 3,446 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 60,646,080 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-292 e scores 0.25, ranking #3,127 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-292 e
Is Kepler-292 e habitable?
No — Kepler-292 e orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is Kepler-292 e?
Kepler-292 e is about 3,446 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 60,646,080 years to get there.
How big is Kepler-292 e compared to Earth?
Kepler-292 e has 2.67 times the radius of Earth.
How long is a year on Kepler-292 e?
One orbit around Kepler-292 takes 12.0 Earth days — short enough that 30 of its years would fit into one Earth year.
