This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. [ 1 ] The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System.
The Solar System belts were formed in the formation and evolution of the Solar System. [6] [7] The Grand tack hypothesis is a model of the unique placement of the giant planets and the Solar System belts. [3] [4] [8] Most giant planets found outside our Solar System, exoplanets, are inside the snow line, and are called Hot Jupiters.
"While more than 70,000 meteorites are known, only 6% had been clearly identified by their composition as coming from the moon, Mars, or Vesta, one of the largest asteroids in the main asteroid belt.
Jupiter's migration across the asteroid belt increases the eccentricities and inclinations of the asteroids, resulting in a 0.5 Myr period of impact velocities sufficient to vaporize metals. If the formation of CB chondrites was due to Jupiter's migration it would have occurred 4.5-5 Myrs after the formation of the Solar System. [29]
The impactor likely formed in the outer solar system before migrating to the asteroid belt. A team of researchers think they know the origin of a massive space rock that hit Earth and killed off ...
The authors, William F. Bottke, David Vokrouhlický, and David Nesvorný, argued that a collision in the asteroid belt 160 million years ago between a 170 km (110 mi) diameter parent body and another 60 km (37 mi) diameter body resulted in the Baptistina family of asteroids, the largest surviving member of which is 298 Baptistina.
For instance, one such space rock 2022 NX 1 was a short-lived “mini-moon” in 1981 and again in 2022. ... They suspect it comes from the Arjuna asteroid belt, a sparse population of small near ...
outer main-belt (a > 2.82 AU) A plot of inner solar system asteroids and planets as of 2006 May 9, in a manner that exposes the Kirkwood gaps. Similar to the position plot, planets (with trajectories) are orange, Jupiter being the outer most in this view. Various asteroid classes are colour coded: 'generic' main-belt asteroids are white.
