Planet Mercury it is the closest to the sun among all those in our solar system, and this would have had a very big impact on the way this planet evolved over time. Researchers recently made an amazing discovery about the planet Mercury, and this is because a huge impact and the sun would have managed to affect to a very large extent the way in which this planet is currently composed.
Planet Mercury it has a core that makes up about 80% of its total composition, while the Earth has a core that represents only 10% of the mass, so we are talking about very different structures. However, not long after the planet Mercury was formed, it seems that a nasty impact threw a good part of the planet's outer mantle into the universe, leaving a core that makes up most of its mass, a situation completely unusual.
Planet Mercury: AMAZING Discovery of the Giant Impact
Planet Mercury it should normally have attracted by its gravitational force a good part of what was thrown from its surface, but the sun had a determining role here. 4 - 4.5 billion years ago, when the impact with the planet Mercury took place, the sun was much "younger", it had a stronger magnetic field, it rotated faster, the solar winds being 10 - 100 times stronger than in the present moment, and that seriously affected what happened.
"A major problem with this idea is that much of the vaporized material ejected from Mercury by a giant impact would condense into solid spheres. These marble pebbles would remain in close-to-Mercury orbits around the Sun and thus simply fall back onto the planet in a few tens of millions of years. The primordial sun during these giant impacts, about 4,5 billion years ago, would have had a stronger magnetic field, faster rotation, and stronger wind. With such a strong solar wind flow, material ejected from Mercury would experience significant drag and be easily removed from the planet's orbit."
Planet Mercury it had thrown into the universe the pieces of its outer mantle that were detached following the impact, and the sun would have been the basis of this process that left the planet in the form we see today. If the sun had not had such a great impact on those pieces of the planet Mercury that were in its orbit following the impact, then now we would be talking about an object with a much denser mass, and with a nucleus that would represent more a little of it.
Planet Mercury will be explored in the following years by a spaceship sent by the Japanese, this will reveal to us other important secrets of the cosmic body.
