Mercury’s crust is thinner than anyone thought, new mathematical calculations reveal. A planetary scientist has used careful mathematical calculations to determine the density of Mercury’s crust, which is thinner than anyone thought. Mercury is small, fast and close to the sun, making the rocky world challenging to visit. Only one probe has ever orbited the planet and collected enough data to tell scientists about the chemistry and landscape of Mercury’s surface. Learning about what is beneath the surface, however, requires careful estimation.

After the probe’s mission end...
