Jupiter - The Elder of the Solar System

Research by German scientists shows that Jupiter is not only the largest planet but also the oldest solar system.

Scientists at Lawrence Livermore National Laboratory, University of Münsterin, Germany, present new evidence that Jupiter is the first planet to form inside the Sun's protoplanetary disk, according to UPI. The research results are published in the Proceedings of the National Academy of Sciences (PNAS) on June 12.

By analyzing tungsten and molybdenum isotopes in iron meteorites, the team found that they were made up of two different types of gas and dust materials, coexisting but still separate from each other after the solar system. Heaven formed about one to 3 million years.

" The most logical mechanism to explain this separation is the process of Jupiter formation, creating a gap in the disk of gas and dust that rotates around the Sun, causing these two sources of materials to not mix. "Thomas Kruijer, the lead author of the study, said.

Kruijer said, Jupiter's solid core formed before the Sun's nebula gas was dissipated. This is consistent with the core deposition model during the creation of a giant gas planet.

According to Daily Science, Jupiter's solid core increased by 20 times the Earth's mass within a million years, then increased to 50 Earth masses until at least 3-4 million years after the solar system formed city. Although the simulation of the solar system's evolution predicts that Jupiter is the first born planet, astronomers have not yet been able to give the exact moment Jupiter formed.

Massive mass and gravity of Jupiter have a significant effect on the planetary system in the solar system. Researchers believe that Jupiter's early birth prevented the formation of any super-Earth.
