April 24 (UPI) -- Researchers have confirmed the presence of a rocky super-Earth orbiting within the habitable zone of a nearby M-type star, a star that is cooler and less luminous than the sun.
The exoplanet, LHS 1140b, features a radius 1.4 times larger than Earth's. LHS 1140b boasts 6.6 times the mass of Earth. Its significant size and mass suggest a rocky composition.
