Kepler-916 b has a radius of 1.76 times that of Earth.

Is Kepler-916 b in the Habitable Zone?

The position of Kepler-916 b relative to the habitable zone of Kepler-916 cannot be precisely determined from the available orbital data.

Too hot Optimistic habitable zone Conservative habitable zone Too cold

Habitable zone of Kepler-916: 0.517–1.238 AU (conservative: 0.655–1.174 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length

A year on Kepler-916 b — one full orbit around Kepler-916 — lasts 32.3 Earth days, shorter than Mercury's 88-day year.

How Was Kepler-916 b Discovered?

Kepler-916 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-916 b?

Kepler-916 b is 2,709.4 light-years (830.7 parsecs) from Earth. Light arriving here tonight left the planet about 2,709 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 47,685,440 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-916 b scores 0.35, ranking #753 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-916 b

Is Kepler-916 b habitable?

Kepler-916 b is not known to orbit within the habitable zone of Kepler-916, and as a super-Earth it is an unlikely candidate for life as we know it.

How far away is Kepler-916 b?

Kepler-916 b is about 2,709 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 47,685,440 years to get there.

How big is Kepler-916 b compared to Earth?

Kepler-916 b has 1.76 times the radius of Earth.

How long is a year on Kepler-916 b?

One orbit around Kepler-916 takes 32.3 Earth days — short enough that 11 of its years would fit into one Earth year.
