TOI-1221 b is a fascinating world discovered in 2023 by the Transiting Exoplanet Survey Satellite, or TESS, using its savvy CCD array to spot its presence as it crossed in front of its star, TOI-1221. This planet delights astronomers by revealing itself through tiny dips in starlight, a cosmic wink captured from the vastness of space. While it doesn’t have a proper name yet, TOI-1221 b orbits its star like a celestial dance partner and invites us to imagine what its skies and surface might be like. Thanks to TESS, this discovery is part of the growing family of exoplanets helping us piece together the endless puzzle of our galaxy’s planetary diversity—all without needing to leave our home planet!
