Part 2/8:
K218B is classified as an exoplanet, meaning it orbits a star outside our solar system. This particular planet, significantly larger than Earth—about 2.6 times its size—exists in a zone considered "habitable." This term refers to the distance between the planet and its star that permits conditions suitable for life as we know it. With an average temperature around 5 degrees Celsius, K218B presents an environment that could sustain life, albeit possibly in microbial forms.
