11 Facts About Asteroid belt

Individual asteroids within the asteroid belt are categorized by their spectra, with most falling into three basic groups: carbonaceous, silicate, and metal-rich .

In 2018, a study from researchers at the University of Florida concluded the asteroid belt was created from the remnants of several ancient planets instead of a single planet.

Planetesimals within the region that would become the asteroid belt were too strongly perturbed by Jupiter's gravity to form a planet.

Orbital resonances occurred where the orbital period of an object in the Asteroid belt formed an integer fraction of the orbital period of Jupiter, perturbing the object into a different orbit; the region lying between the orbits of Mars and Jupiter contains many such orbital resonances.

Current asteroid belt is believed to contain only a small fraction of the mass of the primordial belt.

Since their formation, the size distribution of the asteroid belt has remained relatively stable; no significant increase or decrease in the typical dimensions of the main-belt asteroids has occurred.

One mystery of the asteroid belt is the relative rarity of V-type or basaltic asteroids.

Sometimes, the term "main Asteroid belt" is used to refer only to the more compact "core" region where the greatest concentration of bodies is found.

High population of the asteroid belt makes for a very active environment, where collisions between asteroids occur frequently .

Some most prominent families in the asteroid belt are the Flora, Eunoma, Koronis, Eos, and Themis families.

At the time there was some concern that the debris in the Asteroid belt would pose a hazard to the spacecraft, but it has since been safely traversed by 12 spacecraft without incident.
