Kepler-10 d is a fascinating exoplanet orbiting the star Kepler-10, discovered back in 2023 using the clever radial velocity technique. This crafty method lets astronomers detect planets by observing the subtle wobble they cause in their star’s motion, and it was the HARPS-N Spectrograph at the Roque de los Muchachos Observatory that did the detective work from the ground. While details on its exact size or surface remain a bit mysterious, Kepler-10 d joins its sibling planets around Kepler-10, making this system a rich playground for scientists studying distant worlds. So, while it’s light-years away, Kepler-10 d brings us one step closer to understanding the vast cosmic neighborhood beyond our solar system!
