Kepler-529 c
Kepler-529 c is a super-Earth orbiting Kepler-529 in the constellation Draco. It lies about 2,606 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-529 c?
Kepler-529 c has a radius of 2.00 times that of Earth.
Is Kepler-529 c in the Habitable Zone?
The position of Kepler-529 c relative to the habitable zone of Kepler-529 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-529: 0.932–2.179 AU (conservative: 1.180–2.066 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-529 c — one full orbit around Kepler-529 — lasts 12.8 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-529 c Discovered?
Kepler-529 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-529 c?
Kepler-529 c is 2,606.0 light-years (799.0 parsecs) from Earth. Light arriving here tonight left the planet about 2,606 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 45,865,600 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-529 c scores 0.26, ranking #2,754 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-529 c
Is Kepler-529 c habitable?
Kepler-529 c is not known to orbit within the habitable zone of Kepler-529, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is Kepler-529 c?
Kepler-529 c is about 2,606 light-years from Earth in the constellation Draco. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 45,865,600 years to get there.
How big is Kepler-529 c compared to Earth?
Kepler-529 c has 2.00 times the radius of Earth.
How long is a year on Kepler-529 c?
One orbit around Kepler-529 takes 12.8 Earth days — short enough that 28 of its years would fit into one Earth year.
