This giant world was spotted with the precision of the Coude Echelle Spectrograph, a ground-based instrument that helps astronomers tease out subtle wobbles in a star’s motion caused by orbiting planets. While it doesn’t have a catchy proper name yet, HD 139357 b still stands out as an intriguing world to ponder—likely a hefty, far-flung companion circling its host star in the distant cosmos.
