Kepler-1695 b
Kepler-1695 b is a terrestrial planet orbiting Kepler-1695 in the constellation Cygnus. It lies about 2,581 light-years from Earth and was discovered in 2020 using the transit method.
How Big Is Kepler-1695 b?
Kepler-1695 b has a radius of 1.12 times that of Earth.
Is Kepler-1695 b in the Habitable Zone?
The position of Kepler-1695 b relative to the habitable zone of Kepler-1695 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-1695: 0.678–1.612 AU (conservative: 0.859–1.528 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-1695 b — one full orbit around Kepler-1695 — lasts 4.73 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-1695 b Discovered?
Kepler-1695 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-1695 b?
Kepler-1695 b is 2,580.5 light-years (791.2 parsecs) from Earth. Light arriving here tonight left the planet about 2,581 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 45,416,800 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-1695 b scores 0.30, ranking #1,480 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-1695 b
Is Kepler-1695 b habitable?
Kepler-1695 b is not known to orbit within the habitable zone of Kepler-1695, and as a terrestrial planet it is an unlikely candidate for life as we know it.
How far away is Kepler-1695 b?
Kepler-1695 b is about 2,581 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 45,416,800 years to get there.
How big is Kepler-1695 b compared to Earth?
Kepler-1695 b has 1.12 times the radius of Earth.
How long is a year on Kepler-1695 b?
One orbit around Kepler-1695 takes 4.7 Earth days — short enough that 77 of its years would fit into one Earth year.
