It is commonly accepted that the Asteroid Belt was formed by the partial agglutination of solid material available in that region, which was halted before the formation of a planet, due to the simultaneous appearance of Jupiter. However, for a more complete understanding of the scenario of asteroids formation, one must also take into account their characteristics and implications for the …
More than one thousand transneptunian objects are currently known, but it is estimated that this number can be as big as hundreds of millions. The Kuiper Belt contains at least four dynamically distinct regions of which the most recently determined is the extended scattered disk (ESD), whose objects are also called detached objects. One of the objects belonging to this region, 2004XR190, …
The planetary instability, as proposed by the most recent model of planetary migration, known as jumping-Jupiter, can explain many features of the evolution of the giants planets. This instability is characterized by the fact that the giants planets in the outer solar system, formed in a multi-resonant orbital configuration, underwent several close encounters with one another, after being…
The study of the trans-Neptunian region is relatively recent, with just over 20 years. The increased number of discovered objects revealed a far more complex scenario than what is conjectured. At least four dynamic classes can be defined in the region and it is estimated that the number of real objects can be up to six orders of magnitude higher than the number currently known. The dynami…
