Kepler-402 d is a fascinating exoplanet orbiting the star Kepler-402, discovered back in 2014 by the dedicated Kepler space telescope team using the transit method—a clever technique that spots planets by noticing tiny dips in starlight. This distant world doesn’t have a flashy proper name yet, but it holds a special spot in the cosmic neighborhood as part of the ever-growing family of planets found by Kepler's CCD Array eyes. While we don’t know exactly what this planet looks like up close, its discovery adds a shining star to our understanding of distant solar systems. Floating far beyond our reach in space, Kepler-402 d invites our imaginations to wander the vast universe in search of new planetary adventures!
