Kepler-716 c
Kepler-716 c is a super-Earth orbiting Kepler-716 in the constellation Lyra. It lies about 2,071 light-years from Earth and was discovered in 2020 using the transit method.
How Big Is Kepler-716 c?
Kepler-716 c has a radius of 1.39 times that of Earth.
Is Kepler-716 c in the Habitable Zone?
The position of Kepler-716 c relative to the habitable zone of Kepler-716 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-716: 0.438–1.059 AU (conservative: 0.555–1.004 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-716 c — one full orbit around Kepler-716 — lasts 3.97 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-716 c Discovered?
Kepler-716 c was discovered in 2020 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-716 c?
Kepler-716 c is 2,071.1 light-years (635.0 parsecs) from Earth. Light arriving here tonight left the planet about 2,071 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 36,451,360 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-716 c scores 0.29, ranking #1,685 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-716 c
Is Kepler-716 c habitable?
Kepler-716 c is not known to orbit within the habitable zone of Kepler-716, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-716 c?
Kepler-716 c is about 2,071 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 36,451,360 years to get there.
How big is Kepler-716 c compared to Earth?
Kepler-716 c has 1.39 times the radius of Earth.
How long is a year on Kepler-716 c?
One orbit around Kepler-716 takes 4.0 Earth days — short enough that 92 of its years would fit into one Earth year.
