The planet discovered, known as LHS 3154b, is about 13 times more massive than Earth. As planets go, that’s not unheard of.

A recent study published in Science examines exoplanet LHS 3154b that orbits its parent star in just 3.7 days but is 13.2 times as massive as the Earth with the star being nine times less than our Sun ...

The discovery of LHS 3154b was made using the Habitable Zone Planet Finder (HPF), an astronomical spectrograph developed at Penn State University by a team of scientists led by Suvrath Mahadevan.
