Kepler-653 c
Kepler-653 c is a terrestrial planet orbiting Kepler-653 in the constellation Lyra. It lies about 1,943 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-653 c?
Kepler-653 c has a radius of 0.78 times that of Earth.
Is Kepler-653 c in the Habitable Zone?
The position of Kepler-653 c relative to the habitable zone of Kepler-653 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-653: 0.864–2.043 AU (conservative: 1.095–1.937 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-653 c — one full orbit around Kepler-653 — lasts just 21.6 hours, shorter than Mercury's 88-day year.
How Was Kepler-653 c Discovered?
Kepler-653 c was discovered in 2016 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-653 c?
Kepler-653 c is 1,942.7 light-years (595.6 parsecs) from Earth. Light arriving here tonight left the planet about 1,943 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 34,191,520 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-653 c scores 0.29, ranking #1,948 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-653 c
Is Kepler-653 c habitable?
Kepler-653 c is not known to orbit within the habitable zone of Kepler-653, and as a terrestrial planet it is an unlikely candidate for life as we know it.
How far away is Kepler-653 c?
Kepler-653 c is about 1,943 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 34,191,520 years to get there.
How big is Kepler-653 c compared to Earth?
Kepler-653 c has 0.78 times the radius of Earth.
How long is a year on Kepler-653 c?
One orbit around Kepler-653 takes 0.9 Earth days — short enough that 406 of its years would fit into one Earth year.
