TOI-663 d is a newly discovered exoplanet orbiting the star TOI-663, spotted by the keen eyes of NASA's Transiting Exoplanet Survey Satellite (TESS) in 2024. This distant world was found by catching the subtle dimming of its star as the planet gracefully passed in front, a cosmic game of hide-and-seek played millions of miles away in space. Though we don’t have a fancy proper name for it yet, TOI-663 d invites curiosity as a fresh addition to the growing family of planets beyond our solar system. Thanks to the cutting-edge CCD array aboard TESS, we’re expanding our celestial neighborhood, one transit at a time – making this planet a star in its own right among the universe’s vast ensemble.
