Uranus is the only planet in orbit around the Sun "on its side".
Scientists have speculated why this is happening: the collision of the planet with a mysterious planet at least twice the size of the Earth.
A Durham University astronomer, Jacob Kegrays, showed at a detailed computer simulation that a big stone fell on Uranus, according to Phys.org.
Uranus is a unique planet in the solar system. Melana has a 90 degree angle, as well as her first five moons. According to NASA scientists Jim Green, his magnetic field is also one-sided and does not extend beyond the poles, just like the Earth. He has rings like Saturn.
The computer simulation shows that the collision and change of the Uranus shape occurred in a few hours. Kigrais has placed moving drawings showing the collision of the planet with another mysterious planet and its consequences. The great body that hit Uranus can still hide in the solar system, but it is too far for scientists. This would explain some of the characteristics of planetary rotation and correspond to the theory that the mysterious planet X orbits the Sun outside of Pluto.
The collision occurred 3 or 4 billion years ago, probably before the formation of Uranus satellites. Instead, the satellites were formed. When that happened, the strange inclination of Uranus was an attractive force that pushed the big five satellites to the same kilometer.
According to Kegrais, this also forms the layer of ice that stores the internal heat of Uranus underneath. The surface temperature of Uranus is -166 ° C.
Ice is the main feature of Uranus and its neighbor Neptune. A little more than ten years ago NASA called these two planets "ice giants," the gas giants of Saturn and Jupiter.
