EPIC 201833600 c
EPIC 201833600 c is a terrestrial planet orbiting K2-50 in the constellation Leo. It lies about 840 light-years from Earth and was discovered in 2019 using the transit method.
How Big Is EPIC 201833600 c?
EPIC 201833600 c has a radius of 1.00 times that of Earth.
Is EPIC 201833600 c in the Habitable Zone?
The position of EPIC 201833600 c relative to the habitable zone of K2-50 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on EPIC 201833600 c — one full orbit around K2-50 — lasts 3.96 Earth days, shorter than Mercury's 88-day year.
How Was EPIC 201833600 c Discovered?
EPIC 201833600 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 201833600 c?
EPIC 201833600 c is 839.7 light-years (257.4 parsecs) from Earth. Light arriving here tonight left the planet around the year 1187. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 14,778,720 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 201833600 c scores 0.31, ranking #1,135 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About EPIC 201833600 c
Is EPIC 201833600 c habitable?
EPIC 201833600 c is not known to orbit within the habitable zone of K2-50, and as a terrestrial planet it is an unlikely candidate for life as we know it.
How far away is EPIC 201833600 c?
EPIC 201833600 c is about 840 light-years from Earth in the constellation Leo. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 14,778,720 years to get there.
How big is EPIC 201833600 c compared to Earth?
EPIC 201833600 c has 1.00 times the radius of Earth.
How long is a year on EPIC 201833600 c?
One orbit around K2-50 takes 4.0 Earth days — short enough that 92 of its years would fit into one Earth year.
