Orbiting the quiet red star GJ 9404, discovered in 2023 thanks to the sharp eyes of the HARPS-N Spectrograph at the Roque de los Muchachos Observatory, planet GJ 9404 b is a fascinating newcomer to the exoplanet family. This ground-based find was uncovered using the radial velocity method, which is a clever technique that detects the subtle wobble of a star caused by an orbiting planet. While details like its exact distance from Earth remain a mystery, GJ 9404 b invites astronomers and stargazers alike to imagine a world circling a cool, dim star far beyond our solar system. It’s a wonderful reminder of how much more there is to explore in the vast cosmic ocean.
