The size of the earth remains the same … scientists explain


Al-Jazeera reports that an international team of astronomers from the United States, France and Germany has provided a scientific explanation of the Earth’s small size in the solar system.

According to the French magazine Le Point, author Frederick Luino says that if the solar system had expanded like other groups, the planet’s mass would be 5 to 10 times larger than it is today.

The secret lies in the pressure bumps
But what happened to make our planet so small? In an article published in the journal Nature Astronomy, many scientists sought to answer this question.

According to scientists, the explanation can be found in the nature of the dust rings that formed the planets of the solar system. History of the Solar System 5.56 billion years ago, when the dust and gas clouds began to fall, the Sun was born at the center of this gravitational pull, and after the dust lost its gravitational pull, the planets were born.

Typically, this dust accumulates and forms large rocky planets, mainly minerals and rocks, but this does not happen in the solar system. To solve this puzzle the team drew hundreds of computer models before finding a very definitive description.

According to scientists – “pressure bumps” (transition from a solid state to a gaseous state without passing through the liquid phase) that form as a result of sublimation or sublimation event split the dust cloud into 3 rings. .

As the sun cooled, these bumps moved and collected dust in the form of asteroids (also known as driving asteroids, which are small asteroids orbiting the sun).

The dust of the first ring came together to form pebbles and rocks, and then gradually formed smaller celestial bodies, and finally formed the four planets Mercury, Venus, Earth and Mars.

As for the second ring, far from the Sun, it led to the formation of giant and gaseous planets. For the third ring, it formed dwarf planets and billions of tiny rock bodies, known as the “Khyber belt.”
