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.
Most highly inclined known main-belt asteroid from 1998/10/19-2007/11/01 MPC (467372) 2004 LG: 70.725° June 9, 2004 A Mercury-through Mars-crosser and near-Earth object. MPC: 2007 VR 6: 68.659° November 1, 2007 Most highly inclined known main-belt asteroid from November 1, 2007, to September 26, 2008 MPC: 2008 SB 85: 74.247° September 26, 2008
"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 ...
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 ...
Among the distant minor planets, the icy Kuiper belt object Arrokoth was confirmed to be a contact binary when the New Horizons spacecraft flew past in 2019. [1] The small main-belt asteroid 152830 Dinkinesh was confirmed to have the first known contact binary satellite after the Lucy probe flew by it on November 1, 2023. [31]
