A new study conducted by University of Toronto researchers suggests that a potential fifth gas planet existed in the Solar System during its formation.

We could have one more planet in our solar system if Jupiter had not pushed it out of the region four billion years ago.
Planet ejections take place when two planets come too close to each other and one accelerates so much that it breaks free from the strong gravitational pull of the Sunday. Previous research have instructed this phenomenon is feasible between gasoline giants however failed to have a look at the impact such an occasion would have on the planets’ moons.
The Solar System has always been known to contain only four massive gas planets in its roster of worlds: Neptune, Uranus, Saturn and Jupiter. As said, ejection among gas giants causes a huge violent encounter on the planets’ atmosphere that result to extinguishing the minor bodies orbiting around the planet itself. Moreover, the whereabouts of the ejected orb would certainly add a piquant new angle to perceptions about our supposedly peaceful “family” of planets and moons.
The team then measured the probability of each moon producing its present orbit if its host planet suddenly gets involved in the ejection of a hypothetical planet.
In a study featured in The Astrophysical Journal, Ryan Cloutier and his colleagues at the University of Toronto explored the possibility of a titanic clash between a few of the largest planets in the Solar System. Whereas it might have been able to ejecting a fifth gasoline big from our early photo voltaic system, it could additionally be capable to retain a moon displaying the identical orbit as Callisto. Cloutier and his team developed computer simulations based on the modern activities of Callisto and lapetus, the regular moons that orbit Jupiter and Saturn. Usually, an extremely accelerated spin coupled with the breaking away from the gravitational pull of the Solar would generate a large disturbance to the moon’s orbit. But with Jupiter, issues are totally different.
There was a fifth giant planet in the solar system, but it was ejected after a close encounter with Jupiter, a computer model made by Canadian astronomers suggests.

The icy giant’s current whereabouts are unknown. Astrophysicists speculate that it has joined an estimated millions of “rogue” planets traveling the interstellar space of the Milky Way.
