EPIC 212587672 b
EPIC 212587672 b is a super-Earth orbiting EPIC 212587672 in the constellation Virgo. It lies about 1,044 light-years from Earth and was discovered in 2019 using the transit method.
How Big Is EPIC 212587672 b?
EPIC 212587672 b has a radius of 1.26 times that of Earth.
Is EPIC 212587672 b in the Habitable Zone?
The position of EPIC 212587672 b relative to the habitable zone of EPIC 212587672 cannot be precisely determined from the available orbital data.
Habitable zone of EPIC 212587672: 0.783–1.835 AU (conservative: 0.992–1.740 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on EPIC 212587672 b
The equilibrium temperature of EPIC 212587672 b is about 756 K (483 °C) — hot enough to melt many metals. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on EPIC 212587672 b — one full orbit around EPIC 212587672 — lasts 15.3 Earth days, shorter than Mercury's 88-day year.
How Was EPIC 212587672 b Discovered?
EPIC 212587672 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 212587672 b?
EPIC 212587672 b is 1,043.9 light-years (320.1 parsecs) from Earth. Light arriving here tonight left the planet about 1,044 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 18,372,640 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 212587672 b scores 0.31, ranking #1,188 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
