Welcome to 91 Aquarii b, a giant world orbiting the bright star 91 Aquarii, nestled in the constellation Aquarius! Discovered back in 2013 using the trusty radial velocity method at the Lick Observatory, this exoplanet plays a cosmic game of tug-of-war with its star, which helped astronomers detect its presence. While it doesn’t have a fancy proper name yet, 91 Aquarii b is a gas giant, likely much bigger than Jupiter, making it a heavyweight of its stellar neighborhood. Thanks to the Hamilton Echelle Spectrograph, we peeked into this distant system from here on Earth, unveiling a little more about our universe’s diverse planetary family. Keep dreaming of the stars—91 Aquarii b is just one of many fascinating worlds out there!
