Mercury may have shrunk 30% more than previously believed, new study says; planets radius may have decreased by 7.2 miles

Recent studies indicate that Mercury has shrunk more than scientists previously realized. The presence of impact debris has hindered the visibility of this contraction, shedding light on Mercury's interior features and its metallic core. This discovery offers valuable clues to the planet's geological history and magnetic field evolution. Upcoming explorations, particularly the BepiColombo mission, are set to gather crucial data to validate these revelations.
