Orbit and Year Length
A year on KIC 10525077 b — one full orbit around KIC 10525077 — lasts 854.1 Earth days, longer than an Earth year.
How Was KIC 10525077 b Discovered?
KIC 10525077 b was discovered in 2015 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 KIC 10525077 b?
KIC 10525077 b is 4,765.6 light-years (1,461.2 parsecs) from Earth. Light arriving here tonight left the planet about 4,766 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 83,874,560 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. KIC 10525077 b scores 0.44, ranking #376 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
