Orbit and Year Length
A year on EPIC 206215704 b — one full orbit around EPIC 206215704 — lasts 2.26 Earth days, shorter than Mercury's 88-day year.
How Was EPIC 206215704 b Discovered?
EPIC 206215704 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 206215704 b?
EPIC 206215704 b is 358.4 light-years (109.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1668. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 6,307,840 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 206215704 b scores 0.39, ranking #502 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
