In the distant past, Uranus could face a massive glacial protoplanet that was twice as large as the Earth.
Such a collision led to the displacement of the axis of rotation of the planet, writes Gizmodo. is actually on the side – the plane of the equator is inclined to the plane of its orbit almost at right angles. New evidence suggests that Uranus was broken in a giant collision, resulting in its lateral orientation to the orbital plane.
Uranus rotates not only along an axis that is 98 degrees to its orbital plane, but on Unlike other giant planets, it does not emit more heat than it does. receives from the sun. Its magnetic field also seems to be deformed in relation to the earth. External influences could help explain some of these amazing features.
Scientists have modeled giant influences on Uranus since the early 1990s. At that time, researchers led by Jacob Kegerreys of the University of Durham built a new simulation with the latest data available on the planet. . The authors of the study modeled more than 50 different collision scenarios that showed other events on the planet
The main version was the collision of a young Uranus with an icy object, whose mass exceeded the mass of the Earth twice. At the same time, the collision was not frontal – the protoplanet only touched Uranus on the side, accelerating its rotation. In addition, the rings and satellites of Uranus can be cut during a collision with the object of the parts of the planet.
The remains of the very frozen planet have created a special point of asymmetry in the intestines of Uranus, whose existence is constantly changing. shape
But we must not forget that it's just a simulation. Models can not say exactly what happened; "We really need the next ambitious robotic mission to study Uranus and its diverse satellite system." The gravitational, atmospheric and magnetic mapping of the field could provide new clues, "the scientists point out.
