Iron makes up about 70% of Mercury's total weight making Mercury the most iron-rich planet in the Solar System. On top of this core, lies an outer, rocky shell which is about 350 miles (~550 km) thick. Continue the conversation on Twitter Facebook Contact Us Privacy Policy Image Use Policy
WebApr 11, 2024 · Forming Iron-rich Planets with Giant Impacts. We investigate mantle stripping giant impacts (GI) between super-Earths with masses between 1 M and 20 M. We infer new scaling laws for the mass of the largest fragment and its iron mass fraction, as well as updated fitting coefficients for the critical specific impact energy for catastrophic ... WebThe core of the Earth is composed of iron and other heavy elements (density ~8 gm ⁄ cm 3). In contrast, the mantle and crust are composed of lighter rocks (density ~3 gm ⁄ cm 3). When the Earth formed, the heavy elements sank to the center. Planets with this kind of structure are said to be differentiated.
