GJ 3998 c is a fascinating exoplanet orbiting the star GJ 3998, discovered back in 2016 using the clever radial velocity method. This discovery was made possible by the HARPS-N Spectrograph stationed at the Roque de los Muchachos Observatory, nestled high above the clouds on La Palma. GJ 3998 c is a distant world unlike our own, offering a glimpse into the diverse variety of planets that exist beyond our solar system. While it keeps a steady dance around its cool host star, this planet reminds us how much there is still to explore in the cosmos. It’s a cosmic neighbor discovered right here on Earth with technology that can feel almost like space magic!
