The culprit caused Uranus to tilt to one side

The tilt of the planet up to 98 degrees of Uranus may be due to a collision with a planet with twice the Earth's mass 4 billion years ago.

All planets in the solar system are inclined to the same side, except for Uranus. The north-south axis of the 98-degree-tipped blue-green planet compared to the Sun's orbit, according to Science Alert. Astronomers speculate that in the distant past, Uranus had collided with a planet twice the size of the Earth and as a result was tilted to one side in the study published July 2 in Astrophysical magazine. Journal.

It is possible that the young Uranus collides with an object that has twice the mass of the Earth, causing it to tilt to one side.

The team used simulations on computers, allowing objects of different sizes to crash into Uranus models and observing the impact."We run more than 50 different collision situations, using high-powered supercomputers to see if we can replicate the conditions that shape the planet's evolution. Our findings confirm. The most likely scenario is that Uranus young collides with an object that is twice the mass of the Earth , " said physicist Jacob Kegerreis of Durham University, England.

According to the researchers, the collision event occurred 4 billion years ago, in the early period of the solar system. The collision may help explain some other strange things about Uranus such as the fragile equator and the moon system in the same direction as its neighboring celestial bodies.

If the explosion occurred in a flash, the impact would still be enough for Thien Vuong to tilt to one side without losing the atmosphere, and spraying material rain into orbit. The collision can also create ice and ice inside the planet. This contributes to explain why Uranus has an unusual, asymmetrical magnetic field that is tilted 60 degrees from the axis.
