Mercury, the closest planet to the Sun, has a large heart. A heart in proportion to the size of his coat. And full of iron. Researchers now say that this is due to the magnetic field of our star.
Some missions but they taught , In fact, represents three-quarters of its mass. And its radius is measured to be more than 2,000 km. His coat is no more than 400 kilometers. Characteristics of Mercury becoming a dense planet in our solar system., Among other things, the mass of the nucleus Wednesday was appropriate for its size . Of the center
Astronomers were initially eager to explain this difference by colliding with dramatic effects. A large planet would have been sacrificed and lost most of its envelopes in the catastrophe. Thus shaping the Mercury we know. But still (USA) and Doho University (Japan) now offer another explanation. The density, mass and iron content of the center of a rocky planet are affected by the Sun and its distance. .
Researchers at the University of Doha have cited the Sun’s early magnetic field as the cause of variations in rock and metal components in the cores of four planets: Mercury, Venus, Earth and Mars.https://t.co/UWE1meRVvphttps://t.co/c3HhKPRR4B

Use the sample to study the exoplanets
“Distribution Controlled by the sun’s magnetic field., Explains Professor William McDonough , In one . According to him, in At that time the dust and gas around the sun were spinning and the iron grains were attracted to our magnetic field. . So the planets that started to form nearby have added more iron to their iron.First
This is how astronomers know about the planets in our solar system. But to really confirm this, researchers need to find at least one planetary system similar to ours. A system with Distributed at a greater distance from their host star. If the density of the planets decreases as they move away from the stars, this may indicate that the magnetic field is actually affecting planetary formation.
And so on Harmful. The nucleus also has a majority This is one of the planets It is important to sustain a carbon based life. The problem is that there is no way yet to determine the magnetic properties of a star from observations from our Earth.Can be taken into account in the efforts to describe the combination of Rock. In particular the composition of a planet’s nucleus appears to be critical to its ability to support life. On earth, for example, an iron core Create one It protects our planet
