Kepler-632 b
Kepler-632 b is a mini-Neptune orbiting Kepler-632 in the constellation Cygnus. It was discovered in 2016 using the transit method.
How Big Is Kepler-632 b?
Kepler-632 b has a radius of 2.21 times that of Earth.
Is Kepler-632 b in the Habitable Zone?
The position of Kepler-632 b relative to the habitable zone of Kepler-632 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-632: 0.549–1.312 AU (conservative: 0.695–1.244 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-632 b — one full orbit around Kepler-632 — lasts 31.0 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-632 b Discovered?
Kepler-632 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.
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-632 b scores 0.33, ranking #931 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-632 b
Is Kepler-632 b habitable?
Kepler-632 b is not known to orbit within the habitable zone of Kepler-632, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How big is Kepler-632 b compared to Earth?
Kepler-632 b has 2.21 times the radius of Earth.
How long is a year on Kepler-632 b?
One orbit around Kepler-632 takes 31.0 Earth days — short enough that 12 of its years would fit into one Earth year.
