GJ 3779 b is a fascinating exoplanet orbiting the red dwarf star GJ 3779, discovered back in 2018 using the clever radial velocity method with the CARMENES instrument at Spain’s Calar Alto Observatory. This planet is a compact and intriguing world, circling its cool host star quite closely, making it a warm neighbor in cosmic terms. While it’s not famous for a flashy proper name, GJ 3779 b still holds its charm as an exciting target for understanding planets around smaller stars. Thanks to ground-based observations, this discovery showcases how astronomers continue to unveil distant worlds, adding pieces to the puzzle of planetary systems far beyond our own solar neighborhood.
