Kepler-1736 b has a radius of 3.88 times that of Earth.

Is Kepler-1736 b in the Habitable Zone?

The position of Kepler-1736 b relative to the habitable zone of Kepler-1736 cannot be precisely determined from the available orbital data.

Too hot Optimistic habitable zone Conservative habitable zone Too cold

Habitable zone of Kepler-1736: 0.795–1.859 AU (conservative: 1.007–1.763 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length

A year on Kepler-1736 b — one full orbit around Kepler-1736 — lasts 37.8 Earth days, shorter than Mercury's 88-day year.

How Was Kepler-1736 b Discovered?

Kepler-1736 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-1736 b?

Kepler-1736 b is 4,664.0 light-years (1,430.0 parsecs) from Earth. Light arriving here tonight left the planet about 4,664 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 82,086,400 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-1736 b scores 0.20, ranking #3,863 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
