Kepler-1810 b
Kepler-1810 b is a sub-Neptune orbiting Kepler-1810 in the constellation Lyra. It lies about 3,294 light-years from Earth and was discovered in 2021 using the transit method.
How Big Is Kepler-1810 b?
Kepler-1810 b has a radius of 3.92 times that of Earth.
Is Kepler-1810 b in the Habitable Zone?
The position of Kepler-1810 b relative to the habitable zone of Kepler-1810 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1810: 0.701–1.664 AU (conservative: 0.887–1.578 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1810 b — one full orbit around Kepler-1810 — lasts 101.1 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-1810 b Discovered?
Kepler-1810 b was discovered in 2021 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-1810 b?
Kepler-1810 b is 3,293.8 light-years (1,009.9 parsecs) from Earth. Light arriving here tonight left the planet about 3,294 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 57,970,880 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-1810 b scores 0.40, ranking #469 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
