Kepler-350 b
Kepler-350 b is a super-Earth orbiting Kepler-350 in the constellation Lyra. It lies about 3,121 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is Kepler-350 b?
Kepler-350 b has a radius of 1.85 times that of Earth.
Is Kepler-350 b in the Habitable Zone?
The position of Kepler-350 b relative to the habitable zone of Kepler-350 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on Kepler-350 b — one full orbit around Kepler-350 — lasts 11.2 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.104 AU — closer to its star than Mercury is to the Sun.
How Was Kepler-350 b Discovered?
Kepler-350 b 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-350 b?
Kepler-350 b is 3,120.9 light-years (956.9 parsecs) from Earth. Light arriving here tonight left the planet about 3,121 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 54,927,840 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-350 b scores 0.27, ranking #2,683 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-350 b
Is Kepler-350 b habitable?
Kepler-350 b is not known to orbit within the habitable zone of Kepler-350, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-350 b?
Kepler-350 b is about 3,121 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 54,927,840 years to get there.
How big is Kepler-350 b compared to Earth?
Kepler-350 b has 1.85 times the radius of Earth.
How long is a year on Kepler-350 b?
One orbit around Kepler-350 takes 11.2 Earth days — short enough that 33 of its years would fit into one Earth year.
