Kepler-314 c has a radius of 2.90 times that of Earth.

Is Kepler-314 c in the Habitable Zone?

Kepler-314 c orbits inside the inner edge of the habitable zone of Kepler-314. So close to its star, surface conditions are far too hot for liquid water.

Habitable zone of Kepler-314: 0.632–1.507 AU (conservative: 0.801–1.429 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length

A year on Kepler-314 c — one full orbit around Kepler-314 — lasts 5.96 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.064 AU — closer to its star than Mercury is to the Sun.

How Was Kepler-314 c Discovered?

Kepler-314 c 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-314 c?

Kepler-314 c is 877.0 light-years (268.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1149. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 15,435,200 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-314 c scores 0.22, ranking #3,623 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-314 c

Is Kepler-314 c habitable?

No — Kepler-314 c orbits too close to its star and is too hot for liquid water to exist on its surface.

How far away is Kepler-314 c?

Kepler-314 c is about 877 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 15,435,200 years to get there.

How big is Kepler-314 c compared to Earth?

Kepler-314 c has 2.90 times the radius of Earth.

How long is a year on Kepler-314 c?

One orbit around Kepler-314 takes 6.0 Earth days — short enough that 61 of its years would fit into one Earth year.
