An article published in the journal “Icarus” reports a study on the solar system’s structure that offers a reconstruction of its origins. A team of researchers led by Matt Clement of the Carnegie Institution conducted over 6,000 simulations of the solar system’s evolution that led to the conclusion that Jupiter used to make three revolutions around the Sun in the time it took Saturn to make two revolutions when the two planets had just formed. The results also indicate that there was another planet between Saturn and Uranus that was ejected from the solar system, a conclusion that supports a hypothesis that has been studied for years.
