EPIC 201757695 and Its Sub-Earth Planet

EPIC 201757695 is a star with 0.727 solar masses, 0.655 solar radii, and a temperature of 4520 K. Each of these estimates is smaller or cooler than the Sun's corresponding value. One planet is known to orbit this host.

That planet, EPIC 201757695.02, is a Sub-Earth, meaning its size class places it below Earth's radius. Its radius is 0.908 Earth radii, smaller than Earth's, and it completes an orbit every 2.05 days. Astronomers discovered it in 2020 using the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness; repeated dips help establish orbital periods.
