Kepler-1672 b
Kepler-1672 b is a mini-Neptune orbiting Kepler-1672 in the constellation Cygnus. It lies about 1,276 light-years from Earth and was discovered in 2020 using the transit method.
How Big Is Kepler-1672 b?
Kepler-1672 b has a radius of 2.97 times that of Earth.
Is Kepler-1672 b in the Habitable Zone?
The position of Kepler-1672 b relative to the habitable zone of Kepler-1672 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1672: 0.902–2.108 AU (conservative: 1.143–1.999 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1672 b — one full orbit around Kepler-1672 — lasts 150.9 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-1672 b Discovered?
Kepler-1672 b was discovered in 2020 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-1672 b?
Kepler-1672 b is 1,275.9 light-years (391.2 parsecs) from Earth. Light arriving here tonight left the planet about 1,276 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 22,455,840 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-1672 b scores 0.43, ranking #401 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
