Kepler-1095 b has a radius of 1.21 times that of Earth.

Is Kepler-1095 b in the Habitable Zone?

The position of Kepler-1095 b relative to the habitable zone of Kepler-1095 cannot be precisely determined from the available orbital data.

Too hot Optimistic habitable zone Conservative habitable zone Too cold

Habitable zone of Kepler-1095: 0.667–1.576 AU (conservative: 0.845–1.494 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length

A year on Kepler-1095 b — one full orbit around Kepler-1095 — lasts 4.27 Earth days, shorter than Mercury's 88-day year.

How Was Kepler-1095 b Discovered?

Kepler-1095 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-1095 b?

Kepler-1095 b is 2,584.9 light-years (792.5 parsecs) from Earth. Light arriving here tonight left the planet about 2,585 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 45,494,240 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-1095 b scores 0.29, ranking #1,596 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-1095 b

Is Kepler-1095 b habitable?

Kepler-1095 b is not known to orbit within the habitable zone of Kepler-1095, and as a terrestrial planet it is an unlikely candidate for life as we know it.

How far away is Kepler-1095 b?

Kepler-1095 b is about 2,585 light-years from Earth in the constellation Cygnus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 45,494,240 years to get there.

How big is Kepler-1095 b compared to Earth?

Kepler-1095 b has 1.21 times the radius of Earth.

How long is a year on Kepler-1095 b?

One orbit around Kepler-1095 takes 4.3 Earth days — short enough that 86 of its years would fit into one Earth year.
