A study was recently published in The Astrophysical Journal. According to the study the solar system used to have a 9th planet. The planet was kicked out of the solar system about 4 billion years ago.

The culprit is believed to be another gas planet currently present in the solar system. The list of suspects has been narrowed down to Pluto and Saturn. However the study also indicates it is more likely Jupiter was the bully.
The study was carried out by researchers at the University of Toronto. Scientists have been considering the idea of a 9th planet in the solar system for a long time. The recent study has a new take on it and provides a new aspect of the idea.
The study hypothesized the 9th planet present in the solar system was similar to Neptune and Uranus. The 9th planet if it existed used to circle around the sun. However the gas planet probably got too close to one of other the gas planets.
The close proximity to the gas planet caused the planet to speed up and move away from the sun. The distance from the sun caused it to lose the gravitational pull of the sun. The planet move further out of the solar system and became an ice giant. The 9th planet now presumably floats around space.

Jupiter was pointed out as the culprit for kicking the 9th planet out. Jupiter’s moon Callisto has a 42 percent probability of having survived coming close to the 9th planet. Jupiter also has a higher chance of surviving. Saturn’s moon on the other hand had only a 1 percent probability of survival.
