K2-414 c
K2-414 c is a super-Earth orbiting K2-414 in the constellation Aquarius. It lies about 848 light-years from Earth and was discovered in 2022 using the transit method.
How Big Is K2-414 c?
K2-414 c has a radius of 1.93 times that of Earth.
Is K2-414 c in the Habitable Zone?
K2-414 c orbits inside the inner edge of the habitable zone of K2-414. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of K2-414: 0.332–0.827 AU (conservative: 0.421–0.784 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on K2-414 c
K2-414 c receives 56.13 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on K2-414 c — one full orbit around K2-414 — lasts 6.67 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.055 AU — closer to its star than Mercury is to the Sun.
How Was K2-414 c Discovered?
K2-414 c was discovered in 2022 using the transit method, with observations from K2.
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 K2-414 c?
K2-414 c is 848.1 light-years (260.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1178. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 14,926,560 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. K2-414 c scores 0.28, ranking #2,298 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About K2-414 c
Is K2-414 c habitable?
No — K2-414 c orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is K2-414 c?
K2-414 c is about 848 light-years from Earth in the constellation Aquarius. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 14,926,560 years to get there.
How big is K2-414 c compared to Earth?
K2-414 c has 1.93 times the radius of Earth.
How long is a year on K2-414 c?
One orbit around K2-414 takes 6.7 Earth days — short enough that 55 of its years would fit into one Earth year.
