K2-18b orbits a star over 700 trillion miles away from Earth and is considered potentially habitable because of the amount of starlight it gets; there is also speculation of water vapor existing
K2-18b is a planet with mass roughly 8.6 times that of Earth and a radius 2.6 times larger-sitting in an interesting middle ground between rocky planets and gas giants. Since its initial discovery in 2015 by Kepler Space Telescope, the exoplanet had not been considered as potential, while having the capacity of hosting life, until recent
