EPIC 220554210 c
EPIC 220554210 c is a super-Earth orbiting K2-282 in the constellation Pisces. It lies about 1,619 light-years from Earth and was discovered in 2019 using the transit method.
How Big Is EPIC 220554210 c?
EPIC 220554210 c has a radius of 1.60 times that of Earth.
Is EPIC 220554210 c in the Habitable Zone?
The position of EPIC 220554210 c relative to the habitable zone of K2-282 cannot be precisely determined from the available orbital data.
Habitable zone of K2-282: 0.691–1.641 AU (conservative: 0.875–1.556 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on EPIC 220554210 c — one full orbit around K2-282 — lasts just 16.9 hours, shorter than Mercury's 88-day year.
How Was EPIC 220554210 c Discovered?
EPIC 220554210 c 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 220554210 c?
EPIC 220554210 c is 1,618.7 light-years (496.3 parsecs) from Earth. Light arriving here tonight left the planet about 1,619 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 28,489,120 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 220554210 c scores 0.27, ranking #2,432 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About EPIC 220554210 c
Is EPIC 220554210 c habitable?
EPIC 220554210 c is not known to orbit within the habitable zone of K2-282, and as a super-Earth it is an unlikely candidate for life as we know it.
How far away is EPIC 220554210 c?
EPIC 220554210 c is about 1,619 light-years from Earth in the constellation Pisces. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 28,489,120 years to get there.
How big is EPIC 220554210 c compared to Earth?
EPIC 220554210 c has 1.60 times the radius of Earth.
How long is a year on EPIC 220554210 c?
One orbit around K2-282 takes 0.7 Earth days — short enough that 518 of its years would fit into one Earth year.
