Jupiter ruined early Version of Solar System: Study
A new study has revealed that first version of earth's solar system might have been wrecked by Jupiter. According to the study, the solar system may have once been made up of many super-earths, until the largest planet in the Solar System came.
The study was conducted by Konstantin Batygin, Caltech planetary scientist, and Gregory Laughlin, professor of astronomy and astrophysics at UC Santa Cruz. As per the study, the inner system would have had a number of planets that were bigger than Earth.
Batygin said the study has suggested that inward-outward migration of fifth planet from the sun could have ruined the first version of planets. Jupiter also set the stage for the formation of other planets that the solar system has currently, Batygin added. The scientist also said that the new study fits well with other recent studies in knowing how the solar system has evolved.
According to some recent surveys of exoplanets, about half of the sun-like stars have been orbiting planets, but the systems are very different. The surveys showed that they could have one or more than one worlds that are bigger than earth and orbiting closer to their suns.
Batygin said that it seems like today's solar system is not the common representative of the galactic planetary census. "But there is no reason to think that the dominant mode of planet formation throughout the galaxy should not have occurred here. It is more likely that subsequent changes have altered its original makeup", the scientist added.
There are possibilities that like other systems, earth's solar system had formed planets close to the sun. When Jupiter with radius 69,911 kilometer headed towards the sun, those planets got shifted into overlapping orbits due to gravitational forces, which further led them to smash into one another.
