The collision did not change its orbit around the Sun
CITY OF MEXICO (Notimex) .- New research suggests that the collision of a protoplanet of rock and ice with Uranus, he four billion years ago, produced its inclination
The study of the early formation of the seventh planet of the solar system, conducted by the University of Durham, United Kingdom, in cooperation with NASA scientists, simulated with
Through more than 50 impact simulations, specialists have determined that an object twice the mass of the Earth has impacted the young planet, explained the National Administration of Aeronautics and Space (NASA).
The collision has reformed the planet and set it aside, but it is likely that the crash was not so strong to change significantly its orbit around the Sun.
The investigation of the planet that revolves around an axis, whose inclination is 97.7 degrees from the plane of its orbit around the Sun, is the first of its kind to take into account the atmosphere of the planet in its simulations of impact
NASA said the collision could leave melted ice and unbalanced rock blocks inside the planet, which could explain the magnetic field inclined and off center of Uranus. ice and rock thrown into orbit would have agglomerated to form the rings and moons around the third largest planet in the solar system, now in its newly established rotation.
The findings were published in the journal "The Astrophysical Journal", which shows the early years of Uranus, a medium-sized gaseous planet with a rocky and frozen core.
