Kepler-1600 b has a radius of 3.13 times that of Earth.

Is Kepler-1600 b in the Habitable Zone?

The position of Kepler-1600 b relative to the habitable zone of Kepler-1600 cannot be precisely determined from the available orbital data.

Too hot Optimistic habitable zone Conservative habitable zone Too cold

Habitable zone of Kepler-1600: 0.510–1.227 AU (conservative: 0.646–1.163 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length

A year on Kepler-1600 b — one full orbit around Kepler-1600 — lasts 386.4 Earth days, longer than an Earth year.

How Was Kepler-1600 b Discovered?

Kepler-1600 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-1600 b?

Kepler-1600 b is 3,362.0 light-years (1,030.8 parsecs) from Earth. Light arriving here tonight left the planet about 3,362 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 59,171,200 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-1600 b scores 0.56, ranking #177 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
