Study Finds Mercury Shrinking Faster Than Previously Estimated, BepiColombo Mission to Confirm
New research suggests Mercury is shrinking up to 30% more than earlier estimates, with its radius possibly decreasing by about 7 to 14 miles due to internal cooling. Scientists attribute this contraction to the planet's cooling iron core and mantle, causing surface wrinkles and cliffs. Impact debris may have obscured some shrinkage features, leading to underestimation in past studies. The ongoing BepiColombo mission aims to provide detailed data to confirm these findings and enhance understanding of Mercury's geological history.
