EPIC 206032309 b
EPIC 206032309 b is a terrestrial planet orbiting EPIC 206032309 in the constellation Aquarius. It lies about 526 light-years from Earth and was discovered in 2019 using the transit method.
How Big Is EPIC 206032309 b?
EPIC 206032309 b has a radius of 1.01 times that of Earth.
Is EPIC 206032309 b in the Habitable Zone?
The position of EPIC 206032309 b relative to the habitable zone of EPIC 206032309 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on EPIC 206032309 b — one full orbit around EPIC 206032309 — lasts 2.88 Earth days, shorter than Mercury's 88-day year.
How Was EPIC 206032309 b Discovered?
EPIC 206032309 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 206032309 b?
EPIC 206032309 b is 526.3 light-years (161.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1500. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 9,262,880 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 206032309 b scores 0.33, ranking #883 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
