EPIC 201595106 b
EPIC 201595106 b is a lava world orbiting EPIC 201595106 in the constellation Virgo. It lies about 757 light-years from Earth and was discovered in 2021 using the transit method.
How Big Is EPIC 201595106 b?
EPIC 201595106 b has a radius of 1.57 times that of Earth. Its mass is 7.7 times that of Earth, giving it a density of 11.10 g/cm³ — comparable to rocky planets like Earth (5.51 g/cm³).
Is EPIC 201595106 b in the Habitable Zone?
EPIC 201595106 b orbits inside the inner edge of the habitable zone of EPIC 201595106. So close to its star, surface conditions are far too hot for liquid water.
Habitable zone of EPIC 201595106: 0.713–1.685 AU (conservative: 0.904–1.598 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Temperature on EPIC 201595106 b
The equilibrium temperature of EPIC 201595106 b is about 2,038 K (1,765 °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. It receives 2,852 times the stellar energy that Earth gets from the Sun.
Orbit and Year Length
A year on EPIC 201595106 b — one full orbit around EPIC 201595106 — lasts just 21.1 hours, shorter than Mercury's 88-day year. It orbits at an average distance of 0.018 AU — closer to its star than Mercury is to the Sun.
How Was EPIC 201595106 b Discovered?
EPIC 201595106 b was discovered in 2021 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 201595106 b?
EPIC 201595106 b is 757.0 light-years (232.1 parsecs) from Earth. Light arriving here tonight left the planet around the year 1269. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 13,323,200 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 201595106 b scores 0.29, ranking #1,974 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About EPIC 201595106 b
Is EPIC 201595106 b habitable?
No — EPIC 201595106 b orbits too close to its star and is too hot for liquid water to exist on its surface.
How far away is EPIC 201595106 b?
EPIC 201595106 b is about 757 light-years from Earth in the constellation Virgo. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 13,323,200 years to get there.
How big is EPIC 201595106 b compared to Earth?
EPIC 201595106 b has 1.57 times the radius of Earth and about 7.7 times its mass.
How long is a year on EPIC 201595106 b?
One orbit around EPIC 201595106 takes 0.9 Earth days — short enough that 416 of its years would fit into one Earth year.
