> A thorough investigation published in May 2023 found that the inner core of the Moon is, in fact, [2]a solid ball with a density similar to that of iron . To figure it out once and for all, [astronomer Arthur Briaud of the French National Centre for Scientific Research in France] and his colleagues collected data from space missions and lunar laser-ranging experiments to compile a profile of various lunar characteristics. These include the degree of its deformation by its gravitational interaction with Earth, the variation in its distance from Earth, and its density.

> ... they found that the lunar core is very similar to that of Earth รข" with an outer fluid layer and a solid inner core. According to their modeling, the outer core has a radius of about 362 kilometers (225 miles), and the inner core has a radius of about 258 kilometers (160 miles). That's about 15 percent of the entire radius of the Moon. The inner core, the team found, also has a density of about 7,822 kilograms per cubic meter. That's very close to the density of iron. [...]
The research has been [3]published in Nature .
