HD 231701 b, charmingly named Babylonia, is a giant world orbiting the star HD 231701. Discovered back in 2007 using the clever radial velocity method with the HIRES Spectrometer at the W. M. Keck Observatory, this distant planet shares its star’s neighborhood far beyond our solar system. Imagine a realm where gravity pulls strongly enough to embrace a giant planet, yet Babylonia keeps a steady pace around its star, unseen but detectable through tiny stellar wobbles. Although we can’t visit in person just yet, this celestial newcomer sparks our imagination, hinting at the incredible variety of worlds scattered across the cosmos. Babylonia truly captures the wonder of exploring distant planetary systems from Earth’s own backyard!
