Meet HD 120084 b, a fascinating exoplanet orbiting the star HD 120084, discovered back in 2013 using the clever radial velocity method. This cosmic traveler was found with the sharp eyes of the HIDES Echelle Spectrograph at the Okayama Astrophysical Observatory here on Earth. While we don’t have its exact distance handy, imagine it as a distant companion far beyond our solar system, quietly circling its host star. HD 120084 b was revealed through a method that detects the subtle wobble of its star caused by the planet’s gravitational tug—like feeling a dance partner's pull even when you can’t see their feet. It’s a stellar discovery showing how we can uncover worlds without leaving our own backyard!
