What fraction of Mercury’s total diameter is estimated for its core's radius?
Answer
roughly three-quarters ($ rac{3}{4}$)
The immense size of Mercury’s metal core is further illustrated by comparing its radius to the planet’s overall diameter. Specific estimates place the core's radius at approximately 2,020 kilometers. This measurement corresponds to roughly three-quarters, or $ rac{3}{4}$, of the entire diameter of the planet Mercury. This relationship highlights that the planet is essentially a massive metallic core enveloped by only a relatively thin shell of silicate material, reinforcing its status as the most metal-concentrated planet orbiting the Sun.
