Washington, DC – New work led by Matt Clement of Carnegie reveals the original locations of Saturn and Jupiter. These findings help refine our understanding of the Solar System̵

7;s extraordinary architectural determinants, including the launch of an additional planet between Saturn and Uranus, ensuring that only small, rocky planets, like Earth, form within Jupiter.

When we are young, our sun is surrounded by a rotating disk of gas and dust from which the planets are born. The orbits of the originally formed planets were thought to be close together and circular, but gravitational interactions between larger bodies disturbed the arrangement and caused the tiny giant planets to rapidly change, Create the profile as we see it today.

“We now know that there are thousands of planetary systems in our Milky Way,” Clement said. “But it turns out the arrangement of the planets in our Solar System is very irregular, so we are using the models to reverse engineer and replicate its formation processes. like trying to figure out what happened in a car crash after the fact – how fast the cars went, in which directions, etc. “

Clement and his co-authors – John Chambers of Carnegie, Sean Raymond of the University of Bordeaux, Nathan Kaib of the University of Oklahoma, Rogerio Deienno of the Southwest Research Institute, and André Izidoro of Rice University – conducted 6,000 tissues. Our Solar System’s evolution reveals an unexpected detail about the early relationship of Jupiter and Saturn.

Jupiter in the early days was thought to orbit the Sun three times for every two orbits Saturn completed. But this arrangement could not adequately explain the configuration of the giant planets we see today. The team’s models show that the ratio of the two Jupiter’s orbit to one of Saturn produces the same results as our familiar planetary architecture.

“This indicates that while our Solar System is a little odd, it’s not always the case,” Clement, who is presenting the group’s work at the Planetary Science Division’s virtual meeting American Astronomical Association today. “Furthermore, now that we have established the effectiveness of this model, we can use it to help us look at the formation of planets on the ground, including their own. and perhaps to inform us of the possibility of finding similar systems elsewhere that may have potential for life storage. ”

The model also shows the positions of Uranus and Neptune is shaped by the mass of the Kuiper belt – an icy region on the edges of the Solar System consisting of dwarf planets and the planets in which Pluto Wang is the largest member – and by a giant block of ice. Planets were eliminated in the early Solar System period.
