Scientists say that many asteroids can be leftovers of the world destroyed five

Initially, the solar system was slightly more than clouds of dust and gas, then the cold temperature brought down the sun in the center The neon stars are burned by nuclear fusion, which turns the light in the rotating disk, and soon, this material has been added to the planets, snow giants and the rocky world that builds the solar system we know today

Over the years, asteroids have been considered as the remaining substances in the formation of the planet – pieces of material that they have never manufactured in the form of the planet and which were pulled in the rock belts between Mars and Jupiter.

But according to a study published in the journal Nature Astronomy on Monday, there was once a fragment of the world.Scientists say that 39; a large majority of half a million bodies in the inner asteroid belt can actually be shirpel of five base b bodies called "planets". But the confused classes of this lost world meant that they were ruined to collide, which were broken into pieces, which caused more fragments in a cataclysmic cascade that lasted over 4 billion years.

Katherine Kretke, a global scientist from the Southwestern Research Institute, who did not participate in the study, said this discovery exposes not only the "mystery" of the asteroid belt . It can also help solve the debate about the formation of eight planets including the Earth.

"I find it really exciting to see the weather and see the evidence of the building blocks that created our solar system. "" If we can return the clock and the asteroid belt was made by these great planets, then in reality we say something about the conditions that make up our planet. "

The main authors of the study, the University of Florida astronomer, Stanley Dermot, were not required to study the mystery of the formation of the system He and his allies were looking at the data on the mobility of the bodies in the inner asteroid belt, hoping to discover that the object is leaving the belt – and potentially flies to Earth. worry about the collision of asteroids, the rest ensures that Dermot is still studying this issue.)

But when Dermott began to see the database of objects closest to the Earth, he saw something oddly, the cells were inclined, inclined or inclined to the rest of the solar system.

Dermott said, "We could not think of a force that would produce this distribution." From another side, "If a big asteroid broke down and that there is a sharp incline aison, then there is the same inclination. Scientists have already reported that the asteroids of the semi-inner belt belong to the "family." But Dermot and his colleagues say their analysis reveals that this number is as high as 85 percent.

One of the scientists on the SRR planet, David Nesvorny, said that this discovery corresponds to other observations of the asteroid belt, which were not related to Dermot's studies.The asteroids belong to the same family, which are in orbit in groups and have similar chemical structures.

Nesvorny said, if this is clear, the implication of this idea is that asteroids are actually fragments of large bodies: asteroids are born large. "

This discovery can help solve a question about creating a planet that has troubled scientists over the years. According to the traditional history of the origin of the solar system, the planets were formed gradually from the rise, because the particles in the discs stick with the large pebbles, then a little larger, until they reach their current size.

But when the computer science model tries to recreate this story, then it breaks. Rather than growing, these first planets are exploded after reaching the pebbles. As a result of this process, how can they shape the asteroid belt, leave the entire planet alone?

Enter the "Born Big" hypothesis. Nesvorny and many others now think that after gaining position once in the disc, gravity reaches the pebble stage, quickly pulling the material in large quantities to build a huge new planet. In the internal solar system, he produced small rocky planets such as the Earth; Beside the sun, we have gas giants.

But in the space between Mars and Jupiter, the enormous gravity of the planet's largest solar system has made it difficult to develop a large object, Nesvorny said. The small bodies that had emerged, which were probably one-tenth the size of the planet as the Earth, did not escape the chaos and confrontation to come; They broke up and formed the asteroid belt that we know today.

Some principles remain about this principle. Tim Mccoy, the geologist at Smithsonian's National Museum of Natural History, said most meteorites arriving on Earth do not think that they come from large bodies. And Kretke suggested that if the theory were more than five dozen parents, the theory could work better.

Meanwhile, Nestor noted that the inner girdle is only one-tenth of all asteroids – he hopes to see the analysis applied on the

Dermott said that he and his colleagues plan to d & # 39; address the following question. And a few days, he said, research can be applied to other solar systems. Astronomers have found traces of asteroid belt around Vega and Fomalhaut, only a few dozen light years away.

Dermott said, "It's the next big step, and it happens in our lifetime." development and "What do we need to make planet Earth somewhere else?" There is something we can finally discuss in significant terms. "
