Lunar density measurements

Lunar density measurements help scientists understand the Moon’s internal structure by calculating how much mass is packed into a specific volume. This is done by analyzing the Moon's gravity field through satellite orbit data and measuring how it affects spacecraft trajectories. A higher density indicates a composition rich in heavier materials like metals, typical of a metallic core, while lower density suggests a rocky, less dense interior. These measurements provide insights into the Moon’s formation and geological history, revealing whether it has a core, mantle, and crust, much like Earth.
