Kepler-460 c
Kepler-460 c is a Neptune-like planet orbiting KIC 5437945 in the constellation Lyra. It lies about 4,155 light-years from Earth and was discovered in 2016 using the transit method.
How Big Is Kepler-460 c?
Kepler-460 c has a radius of 5.52 times that of Earth.
Is Kepler-460 c in the Habitable Zone?
The position of Kepler-460 c relative to the habitable zone of KIC 5437945 cannot be precisely determined from the available orbital data.
Habitable zone of KIC 5437945: 1.083–2.520 AU (conservative: 1.372–2.389 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on Kepler-460 c — one full orbit around KIC 5437945 — lasts 220.1 Earth days, between the years of Mercury (88 days) and Earth (365 days).
How Was Kepler-460 c Discovered?
Kepler-460 c 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-460 c?
Kepler-460 c is 4,155.3 light-years (1,274.0 parsecs) from Earth. Light arriving here tonight left the planet about 4,155 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 73,133,280 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-460 c scores 0.26, ranking #2,912 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
