Kepler-1016 c
Kepler-1016 c is a sub-Neptune orbiting Kepler-1016 in the constellation Cygnus. It lies about 4,575 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-1016 c?
Kepler-1016 c has a radius of 3.68 times that of Earth.
Is Kepler-1016 c in the Habitable Zone?
The position of Kepler-1016 c relative to the habitable zone of Kepler-1016 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1016: 0.760–1.788 AU (conservative: 0.962–1.695 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1016 c — one full orbit around Kepler-1016 — lasts 105.7 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-1016 c Discovered?
Kepler-1016 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-1016 c?
Kepler-1016 c is 4,575.4 light-years (1,402.8 parsecs) from Earth. Light arriving here tonight left the planet about 4,575 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 80,527,040 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-1016 c scores 0.33, ranking #889 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
