Planets of the inner solar system – Mercury, Venus, Earth and Mars – are small, dry and rocky, unlike Jupiter, Saturn, Uranus and Neptune in the outer system, which is larger and more capable. more water and volatile elements.
According to its wisdom, Jupiter was the first to be created because the solar system evolved from a gas disk and dust about 4.5 billion years ago. The vast planet cut the disc into an inner and outer region and effectively stopped the exchange of materials between the two.
In research published in the journal Science, experts drawn from the University of Zurich, ETH Zurich federal institute of technology, Oxford University, LMU Munich and BGI Bayreuth present a new theory.
Using computer simulations, they found that the two solar systems were formed in two different waves. They argue that the first building blocks of the inner planets – known as planetesimals – appeared at the earliest stages of the sun’s formation, with a key role played not by Jupiter but by the line snow, made up of a water valve at a certain distance from the sun. Some of this valve was trapped on dust particles, which came together to form the planes.
