The scientific community dedicated to analyzing the elements that make up the solar system continues its quest to learn more about the structure of the Earth, the universe, and its components. Recently, a team from the French National Center for Scientific Research, led by French astronomer Arthur Briaud, explicitly described the composition of the Moon’s inner core..
In the research paper, evidence is presented of the similarity that Natural satellite gifts with the interior of the Earth in terms of the elements that make them up and the distance from the center of the inner cores to the planetary crust (radius length).
What is inside the moon?
The journal Nature along with a French research center reported that the inner core of the Moon is solid. With a radius of 258 kilometers, the team found that the density of the deepest part of the satellite is approximately 7,822 kilometers per cubic meter. This figure is close to iron densitya major component of Earth’s inner central region.

The results of this study, says Arthur Briaud, confirm NASA’s 2011 findings via Apolo program. In it, concrete indications of an inner core of the Moon similar to the Earth’s core were found. Briaud also points out that the similarity of the nuclei presents certain consequences in evolution of the moon.
What was the moon’s magnetic field?
The Nature magazine mentions that the moon had magnetic fields at some point. The generation of this force is generated by the movement and convection of the inner cores space bodies. Therefore, it is vital to know the composition of the satellite’s deep zone in order to know the reason for its disappearance.

The report also supports the scenario lunar bombardment in the first 1 billion years of the solar system. To verify this conclusion, we can talk about the time in which the Apollo project found its presence small magnetic fields on the lunar surface, so there is important information that confirms that the Moon had a greater magnetic influence.
How can you analyze the composition of the moon?
The way to analyze the internal composition of the Moon and in general all the elements of the solar system is through seismic data. When an earthquake occurs, it causes it acoustic waves. This allows the planet’s material to be examined, helping scientists create a detailed map of the object’s interior.

The Apollo missions, carried out between 1969 and 1972, collected monthly seismic data. However, technological limitation had an impact on mission duration and placement seismometer, Therefore, the ability to analyze small telluric motions was difficult.
As a result of this problem, Arthur Briaud and his team found in experiments with laser into space an effective way to study the profile properties of the moon. Among the relevant aspects were found such points as the degree of lunar deformation in its gravitational interaction with the Earth, changes in its distance and density.
Who the only satellite that earth has?
The Moon is the only natural satellite that the Earth has and is also the fifth largest satellite in the Solar System. Although the Moon appears to be the brightest object in the universe after the Sun, the Moon has a dark surface with light reflection similar to that of carbon. The regular cycles of this culturally influence mythology, art and the calendar.
