K2-18 c is a fascinating exoplanet orbiting the star K2-18, discovered back in 2017 using the clever radial velocity technique with the HARPS Spectrograph at the La Silla Observatory. While its sibling K2-18 b grabbed headlines for its potential habitability, K2-18 c adds another exciting chapter to this stellar neighborhood. This world is a bit of a mystery, lurking close to its star and probably not the cozy type for life as we know it, but it’s a shining example of what careful ground-based observations can reveal about distant solar systems. A visit to K2-18 c might not promise a vacation spot, but it’s an intriguing destination for those curious about the diverse worlds beyond our own cosmic backyard!
