Uranus underwent Collision somewhere in its History thereby Changing its Nature. A massive object roughly twice the size of Earth hit Uranus and Titled the planet to side.

During the course of its evolution, Uranus took part in a collision with a large object which caused its tilt to go out of whack. It is obvious that whereas other planets are aligned with the sun in the solar system, Uranus happens to tell a different tale.

It is not only slightly disturbed in its axis in comparison with the sun, but it is also strangely much more frigid than Neptune which lies further afield. The object which struck this planet may have done its job a short while ago in its evolution. Yet the exact time remains a mystery.

The astronomers made simulated models of Uranus in order to find out what might have happened in its history. Some of the small-scale collisions were tested 50 times in order to reveal the conditions which may have caused Uranus to undergo the abnormality in its axis in its history.

Uranus has a mass which is 14 times that of our planet. Also, it has a very large diameter. The massive object which hit it may well have been a proto-planet. As for the rocks and ice layers that formed in the planet, they too were a result of this proto-planet’s collision with it.

The extremely cold climate of Uranus was probably due to being thrown out of whack by the outer object. Scientists used supercomputers to make the simulations which gave them solid answers to tough questions regarding the unique case that is Uranus.

Furthermore, some of the moons of Uranus also show the effects of the impact that the planet underwent in its history. Even the magnetic field of Uranus is weird in its nature.

It seems Uranus is an individual case since it underwent a completely shocking impact somewhere in its evolutionary past which rewrote the rules according to which it operated in the solar system.

The findings of this study got published in The Astrophysical Journal.
