Kepler-295 d
Kepler-295 d is a super-Earth orbiting Kepler-295 in the constellation Lyra. It lies about 5,542 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is Kepler-295 d?
Kepler-295 d has a radius of 1.36 times that of Earth.
Is Kepler-295 d in the Habitable Zone?
Kepler-295 d orbits inside the inner edge of the habitable zone of Kepler-295. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of Kepler-295: 0.640–1.516 AU (conservative: 0.811–1.437 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-295 d — one full orbit around Kepler-295 — lasts 33.9 Earth days, shorter than Mercury's 88-day year. It orbits at an average distance of 0.192 AU — closer to its star than Mercury is to the Sun.
How Was Kepler-295 d Discovered?
Kepler-295 d was discovered in 2014 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-295 d?
Kepler-295 d is 5,542.0 light-years (1,699.2 parsecs) from Earth. Light arriving here tonight left the planet about 5,542 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 97,539,200 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-295 d scores 0.30, ranking #1,482 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-295 d
Is Kepler-295 d habitable?
No — Kepler-295 d orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is Kepler-295 d?
Kepler-295 d is about 5,542 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 97,539,200 years to get there.
How big is Kepler-295 d compared to Earth?
Kepler-295 d has 1.36 times the radius of Earth.
How long is a year on Kepler-295 d?
One orbit around Kepler-295 takes 33.9 Earth days — short enough that 11 of its years would fit into one Earth year.
