Kepler-479 b
Kepler-479 b is a mini-Neptune orbiting Kepler-479 in the constellation Lyra. It lies about 1,125 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-479 b?
Kepler-479 b has a radius of 2.12 times that of Earth.
Is Kepler-479 b in the Habitable Zone?
The position of Kepler-479 b relative to the habitable zone of Kepler-479 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-479: 0.517–1.238 AU (conservative: 0.654–1.173 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-479 b — one full orbit around Kepler-479 — lasts 12.5 Earth days, shorter than Mercury's 88-day year.
How Was Kepler-479 b Discovered?
Kepler-479 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-479 b?
Kepler-479 b is 1,124.9 light-years (344.9 parsecs) from Earth. Light arriving here tonight left the planet about 1,125 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 19,798,240 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-479 b scores 0.28, ranking #2,198 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About Kepler-479 b
Is Kepler-479 b habitable?
Kepler-479 b is not known to orbit within the habitable zone of Kepler-479, and as a mini-Neptune it is an unlikely candidate for life as we know it.
How far away is Kepler-479 b?
Kepler-479 b is about 1,125 light-years from Earth in the constellation Lyra. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 19,798,240 years to get there.
How big is Kepler-479 b compared to Earth?
Kepler-479 b has 2.12 times the radius of Earth.
How long is a year on Kepler-479 b?
One orbit around Kepler-479 takes 12.5 Earth days — short enough that 29 of its years would fit into one Earth year.
