Scientists have put forward a new hypothesis for the formation of the Earth: it was formed longer than previously thought, and under the huge influence of Jupiter

Astronomers have proposed a new hypothesis about the formation of the Earth. This is supported by mathematical modeling. This theory does not contradict the existing explanation. Nature Astronomy published the results.

The most popular theory states that the Earth formed approximately 4.567 billion years ago, from the debris of most asteroids, chondrites and cosmic dust. However, no other asteroids with similar compositions have been found. Models suggest that the Earth should have more light elements, such as hydrogen and helium. Scientists have offered many explanations. For example, some scientists believe that heat released by asteroid particle collisions could vaporize lighter elements.

The new study’s authors found that heat could have destroyed heavier substances. This did not occur. They offer an alternative explanation. Planetesimals may have played a role in the creation of the Earth. The mass of these solid bodies orbiting around protostars is gradually increasing as they attract more dust particles. This could mean that the process of forming the Earth is slow. This could also explain inconsistencies within the composition of the planet. Planetesimals may have a different composition. Mathematical modeling was used to prove the possibility of the authors’ hypothesis. It also showed Jupiter’s huge influence on the formation Mercury, Venus and Earth.
