Meet 4 UMa b, a jovial giant dancing around the star 4 Ursae Majoris, discovered back in 2006 thanks to the keen eyes of the Thueringer Landessternwarte Tautenburg team using the Coude Echelle Spectrograph. This exoplanet cleverly reveals itself by the subtle wobble it causes in its host star, a trick spotted through the radial velocity method. While it doesn't have a fancy proper name yet, 4 UMa b certainly earns its place among the cosmic big leagues as a gas giant companion in the constellation Ursa Major. It’s a fantastic example of how ground-based observations can unveil distant worlds, adding charm and wonder to our ever-growing catalog of exoplanets beyond our solar system.
