EPIC 201497682 b
EPIC 201497682 b is a terrestrial planet orbiting EPIC 201497682 in the constellation Leo. It lies about 825 light-years from Earth and was discovered in 2019 using the transit method.
How Big Is EPIC 201497682 b?
EPIC 201497682 b has a radius of 0.69 times that of Earth.
Is EPIC 201497682 b in the Habitable Zone?
The position of EPIC 201497682 b relative to the habitable zone of EPIC 201497682 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on EPIC 201497682 b — one full orbit around EPIC 201497682 — lasts 2.13 Earth days, shorter than Mercury's 88-day year.
How Was EPIC 201497682 b Discovered?
EPIC 201497682 b was discovered in 2019 using the transit method, with observations from K2.
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 EPIC 201497682 b?
EPIC 201497682 b is 825.3 light-years (253.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1201. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 14,525,280 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. EPIC 201497682 b scores 0.29, ranking #1,923 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
