K2-315b is an exoplanet located 185.3 light years away from Earth.[1][2] It orbits the red dwarf K2-315.
Discovery
K2-315b was discovered in 2020 by astronomers in an observatory using the Kepler space telescope.[3] It is also nicknamed the "Pi Planet" because it takes approximately 3.14 days to orbit the host star.[4]
Physical properties
The planet is thought to be a small rocky planet, even though composition is unknown.[4] 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 0.95 times of Earth.,[5] very similar to Venus.
