Uranus did not recover from severe childhood trauma

Uranus is a strange planet. Not only because of its ambiguous English name. He is also a stranger. One of its most bizarre features is the tilt. Uranus revolves around the sun, we can say, lying on the side, and each pillar turns to our star every 42 years. The 1965-2000 Astrophysical Journal an international team of researchers, reconstructed the imagery of this glacial giant with the aid of complex simulations, with complex simulations. After 50 different scenarios of crash scenarios, they believe that Uranus struck an object about twice as heavy as the Earth, which was probably composed of rocks and ice. This happened at the age of the solar system, about 4 billion years ago

The collision did not only affect the tilt. Researchers are convinced that this can explain the surprisingly low temperature of the planet. "Uranus rotates to the side, and its axis with all the other planets in the solar system forms an almost stable angle," says the main author of the article, "Uranium turns on the side Jacob Kegerreis, Ph.D. student at Durham University. "In practice, this caused a powerful blow, but we know very little about how it actually happened and what kind of cataclysm the planets caused "

" Our tests confirm that it is more likely that the young Uranus doubled – if not more so – a mbadive object on the Earth, which led him to the side and began the processes who formed the planet as we see it now. "

Based on the simulation, the most likely scenario is that the object struck Uranus.This changed the tilt of the planet, but in practice all the time. atmosphere remained on the spot.The impact could have contributed to the formation of the rings and satellites of the planet.The energy of such impact could have thrown into orbit enough material that could have formed Some of the nearest satellites In addition, existing satellite orbits could have been modified

Violent collisions in the emerging solar system were no more rare.Our own Moon is the result of this Earth collisional, and the other, the size of Mars, the result of the shock of the planet (Thae). Uranus is similar to the most common type of exoplanets found in these discoveries, and so such studies provide a better understanding of planetary systems and their ability to sustain life.
