Did We Once Have Another Planet In Our Solar System?

As unusual as this theory sounds, apparently Saturn may have been considered as a culprit as well:

But researchers haven’t been able to explain until now what could have happened to that extra planet, with both Jupiter and Saturn named as potential culprits for doing the kicking out.

So the team decided to look at the trajectories of Callisto and Iapetus – two of the regular moons orbiting Jupiter and Saturn respectively. Using computer models, they investigated the likelihood of the moons having the same orbit as they do today if they’d been involved in a mass planetary ejection 4 billion years ago.

“Ultimately, we found that Jupiter is capable of ejecting the fifth giant planet while retaining a moon with the orbit of Callisto,” said Cloutier. “On the other hand, it would have been very difficult for Saturn to do so because Iapetus would have been excessively unsettled, resulting in an orbit that is difficult to reconcile with its current trajectory.”

Does this seem plausible to you?  And if there was a rogue planet, do you think we could pick it up via radio telescope?  Feel free to comment with your ideas.

    A sumerian tablet that is 6000 years old says yes and they know the size correlation of the planets and what order they were in and that Uranus was green in color and that Neptune and Uranus were twin planets so if they knew all that and said another planet is there then yea

    Pluto is not a planet. It was one of Saturn’s moons and it doesnt fit the model. Jupiter Saturn uranus and neptune are all gas giants and then u have a lil solid mass object

    I know but I was born in 1962 we were taught it was a planet all through school.They dismissed as a planet much later..I was trying to be funny
