Exoplanet Transiting Sub Neptune Habitable Zone M Dwarf Hycean Candidate

description K2-18b Overview

K2-18b is a sub-Neptune exoplanet orbiting the M dwarf star K2-18. Located within its star’s habitable zone, it has garnered significant attention due to potential liquid water on its surface. Scientists are studying this planet to understand atmospheric compositions and assess conditions suitable for life, particularly focusing on “hycean” environments – those potentially containing oceans and substantial cloud cover. Research is primarily conducted by astronomers investigating exoplanets and the possibility of habitable worlds beyond our solar system.
