K2-315b is an exoplanet located 185.3 light years away from Earth in the southern zodiac constellation Libra.[3][4] It orbits the red dwarf K2-315.

Discovery

K2-315b was discovered in 2020 by astronomers in an observatory using the Kepler space telescope.[1] It is also nicknamed the "Pi Planet" because it takes approximately 3.14 days to orbit the host star.[5]

Physical properties

The planet is thought to be a small rocky planet, even though composition is unknown.[5] Since it orbits very close to its star, it is too hot to host life, due to it having a scorching temperature of 450 K. Not much is known about it because it was just discovered, but it is similar to Earth, having a radius 95% that of Earth,[6] very similar to Venus, but has 81% Earth's mass.[2]
