Part 2/10:
One of the first noticeable aspects is Mercury’s coloration. Unlike the typical gray tones associated with many celestial bodies, Mercury actually displays color variations, adding to its visual appeal. Compositionally, the planet is roughly 70% metallic materials and 30% silicate rocks, resulting in one of the highest densities in the solar system—about 5.427 g/cm³, just slightly less than Earth’s 5.51 g/cm³. This high density indicates a significant metal core, which has profound implications for its magnetic field and geological history.
