Mercury’s radius is shrinking rapidly! Smallest planet in solar system loses 11 kilometres since formation; scientists warn

Recent research indicates Mercury, the solar system's smallest planet, is shrinking due to its cooling interior. As Mercury's core loses heat, the crust adjusts, forming thrust faults and scarps. New measurements reveal a radius decrease of 2.7 to 5.6 kilometers, offering insights into Mercury's tectonic activity and geological evolution, enhancing our understanding of small rocky planets.
