The simulations showed that Mars originated on the outer edges of one of the rings, so that it didn’t find much material during its formation, it became small in size.
An international research team has found that the sun, sometime around 4 to 5 billion years ago, was surrounded by 3 huge rings of interstellar gas and dust, which explains one of the biggest planetary mysteries now.
Whatsapp studying Published in the journal Nature Astronomy, this research team used a super-computer simulation in which the current solar system evolution data, as well as data obtained by researchers from other star systems in the Milky Way, were repeated hundreds of times, based on on different packets of data.
But the surprise for the team, according to Official statement Released by Rice University, which participated in the study on January 4, the simulation produced the most accurate description of the solar system in its current condition, as the asteroid belt appeared between Mars and Jupiter and another belt in the background of the planet Neptune (Kiper Belt). ), as well as Earth, Mars, Venus and Mercury all took stable and semi-circular orbits.
In addition, the masses of the inner planets were just as accurate as reality, including Mars, which is usually one of the planets produced by previous simulations incorrectly, as during some previous simulations its size reached 10 times that of Earth, according to the new study.
But in this context, the new simulations predicted that the sun was surrounded, at the birth of the solar system, by enormous rings of gas and dust, similar to the rings of Saturn. This revolutionary idea answers a question that has long puzzled scholars in this regard. Why is the Earth so big?
It is known that planets in this range of their star are usually “super-Earths”, a term that describes rocky planets that are larger than Earth but still smaller than gaseous planets such as Neptune and Uranus.
Here the ring hypothesis succeeds in explaining this, because it gives a limited amount of matter to the region in which the inner planets such as Mercury, Venus, Earth and Mars arose. It became small.
