How do scientists measure shrinkage?

Scientists analyse images of Mercury's surface, looking for features like 'lobate scarps' – cliff-like structures formed when the crust buckles. By mapping these features and understanding how they relate to the planet's overall shape, researchers can estimate how much the planet has contracted. The new study found more of these features than expected.
