New evidence indicates Mercury's greater size reduction
Recent research indicates that Mercury has shrunk up to 30% more than previously believed, losing about 14.5 miles in diameter since its formation. This significant contraction is linked to the planet's cooling process, which causes its outer layers to crumple and crack, though impact debris has obscured some surface features. Future observations from two new orbiters arriving at Mercury in 2026 aim to provide more accurate insights into the planet's interior and evolutionary history.
