Number of asteroids in the main belt as a function of their semimajor axis (a). The dashed lines indicate Kirkwood gaps, while colors designate the following zones: I: inner main-belt (a < 2.5 AU) II: middle main-belt (2.5 AU < a < 2.82 AU) III: outer main-belt (a > 2.82 AU)

Early in the life of the solar system, dust and rock circling the sun were pulled together by gravity into planets. But not all of the ingredients created new worlds. A region between Mars and Jupiterbecame the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite g...
Most of the asteroids in the main belt are made of rock and stone, but a small portion of them contain iron and nickel metals. The remaining asteroids are made up of a mix of these, along with carbon-rich materials. Some of the more distant asteroids tend to contain more ices. Although they aren't large enough to maintain an atmosphere, but there i...
Asteroids have more than enough gold, plus other precious metals, to provide a few lifetimes' worth of fortunes. But there are plenty of other reasons asteroids are valuable. But how do we get these metals from these faraway asteroids? Perhaps the best way is to bring the spacerocks to Earth. Most of the metals we use in our everyday lives are buri...
The main belt lies between Mars and Jupiter, roughly two to four times the Earth-sun distance, and spans a region about 140 million miles across. Objects in the belt are divided into eight subgroups named after the main asteroids in each group. These groups are the Hungarias, Floras, Phocaea, Koronis, Eos, Themis, Cybeles and Hildas. Although Holly...
Johann Titius, an 18th-century German astronomer, noted a mathematical pattern in the layout of the planets and used it to predict the existence of one between Mars and Jupiter. Astronomers scoured the heavens in search of this missing body. In 1800, 25 astronomers formed a group known as the Celestial Police, each searching 15 degrees of the Zodia...

These bodies were originally designated main-belt comets (MBCs) in 2006 by astronomers David Jewitt and Henry Hsieh, but this name implies they are necessarily icy in composition like a comet and that they only exist within the main-belt, whereas the growing population of active asteroids shows that this is not always the case.
NASA estimates that between 1.1 and 1.9 million asteroids in the asteroid belt are larger than 1 kilometer in diameter. Millions are smaller. Approximately 8% of known main belt asteroids are similar in composition to 16 Psyche.
28 de feb. de 2019 · The Main Belt: A Gateway to the Formation and Early Evolution of the Solar System | Planetary News. Workshop, Sardinia, Italy | June 4-7, 2019. The Main Asteroid Belt is at the boundary of the inner and outer solar system. It marks a transition region from the rocky volatile-poor inner terrestrial planets to the outer gaseous and icy giant planets.
An asteroid with a mean distance from the Sun of 2.50 AU, for example, makes three circuits…. Within the main belt are groups of asteroids that cluster with respect to certain mean orbital elements (semimajor axis, eccentricity, and inclination).
COSMOS - The SAO Encyclopedia of Astronomy › M. Main Asteroid Belt. The main asteroid belt is estimated to contain millions of objects and is located between the orbits of Mars and Jupiter. The Trojan asteroids are a separate group of asteroids lying outside the main asteroid belt and sharing an orbit with Jupiter.
