Kepler-952 b
Kepler-952 b is a cold gas giant orbiting Kepler-952 in the constellation Lyra. It lies about 4,254 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-952 b?
Kepler-952 b has a radius of 7.65 times that of Earth, or 0.68 times the radius of Jupiter.
Is Kepler-952 b in the Habitable Zone?
The position of Kepler-952 b relative to the habitable zone of Kepler-952 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-952: 0.733–1.729 AU (conservative: 0.928–1.639 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-952 b — one full orbit around Kepler-952 — lasts 130.4 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-952 b Discovered?
Kepler-952 b 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-952 b?
Kepler-952 b is 4,253.9 light-years (1,304.3 parsecs) from Earth. Light arriving here tonight left the planet about 4,254 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 74,868,640 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-952 b scores 0.29, ranking #1,862 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
