Kepler-511 b
Kepler-511 b is a cold gas giant orbiting Kepler-511 in the constellation Lyra. It lies about 2,127 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-511 b?
Kepler-511 b has a radius of 6.35 times that of Earth, or 0.57 times the radius of Jupiter.
Is Kepler-511 b in the Habitable Zone?
The position of Kepler-511 b relative to the habitable zone of Kepler-511 cannot be precisely determined from the available orbital data.
Habitable zone of Kepler-511: 1.090–2.563 AU (conservative: 1.381–2.430 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-511 b — one full orbit around Kepler-511 — lasts 296.6 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-511 b Discovered?
Kepler-511 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-511 b?
Kepler-511 b is 2,126.5 light-years (652.0 parsecs) from Earth. Light arriving here tonight left the planet about 2,127 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 37,426,400 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-511 b scores 0.32, ranking #984 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
