A Lunar Core Similar to Earth’s
An international team of researchers has confirmed that the Moon’s inner core is solid and is surrounded by a fluid layer. The lunar core, with a radius of about 258 km, accounts for about 15% of the Moon’s total radius. Its density, similar to that of iron, suggests a metallic composition akin to Earth’s. This revelation is a pivotal breakthrough in understanding the Moon’s internal structure and resolves years of uncertainty and competing theories.
