Kepler-1630 b
Kepler-1630 b is a mini-Neptune orbiting Kepler-1630 in the constellation Cygnus. It lies about 1,080 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-1630 b?
Kepler-1630 b has a radius of 2.19 times that of Earth.
Is Kepler-1630 b in the Habitable Zone?
The position of Kepler-1630 b relative to the habitable zone of Kepler-1630 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1630: 0.335–0.820 AU (conservative: 0.425–0.777 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1630 b — one full orbit around Kepler-1630 — lasts 510.0 Earth days, longer than an Earth year.
How Was Kepler-1630 b Discovered?
Kepler-1630 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-1630 b?
Kepler-1630 b is 1,080.3 light-years (331.2 parsecs) from Earth. Light arriving here tonight left the planet about 1,080 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 19,013,280 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-1630 b scores 0.44, ranking #352 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
