Solar System's smallest planets shrinking rapidly
The study indicates that Mercury continues to shrink at a much faster rate than previously estimated, with it having lost about 22 kilometers of its size since its formation 4.5 billion years ago due to cooling processes. Using data from NASA's Messenger spacecraft, researchers discovered signs of contraction far greater than previously thought, suggesting that this shrinking rate is 30% higher than earlier estimates. The findings imply that Mercury's volume decline could provide deeper insights into planetary formation and evolution, and this study represents an important step toward understanding the internal processes that may occur in other planets.
