GJ 273 b is an intriguing exoplanet orbiting the bright red dwarf GJ 273, discovered in 2017 using the trusty HARPS Spectrograph at the La Silla Observatory. This ground-based find was made by detecting the planet’s subtle gravitational tug on its star through radial velocity measurements. GJ 273 b occupies a cozy spot in its star’s habitable zone, where conditions might just be right for liquid water—making it a charming candidate for future studies seeking potentially life-friendly environments. Though it’s a bit over a dozen light-years away, GJ 273 b invites us to dream about distant worlds and the fascinating variety of planets lurking just beyond our cosmic doorstep.
