Example text

Asteroids that may be in this region are named Vulcan objects, but have proven difficult to observe because of their proximity to the Sun. The second large stable region for asteroids in the inner solar system is known as the main belt, divided into several sub-belts, between the orbits of Mars and Jupiter. main asteroid Belt By far the largest number of asteroids in the inner solar system are located in the main asteroid belt between the orbits of Mars and Jupiter. 1 and 2 million asteroids in this belt with diameters greater than half a mile (1 km), comprising about 95 percent of the known asteroids.

Like planets, asteroids orbit the Sun and rotate on their axes, although many asteroids have more of a tumbling motion than the spinning typical of planets. Many asteroids have unusual shapes, and it is not unusual for asteroids to resemble familiar objects, like giant dogbones (216 Kleopatra, 135 miles; 217 km long) tumbling through space. Typical periods of rotation (corresponding to the length of a day) range from 3 hours to several Earth days, with most falling around periods of 9 hours. Many asteroids are really collections of blocks of rubble all rotating in the same place.

The nonchrondrites are divided into primitive and differentiated types. The differentiated nonchondrites have three groups, including the achondrites, stony irons, and irons. These groups are based on the chemistry and texture of the meteorites, and reflect their origin. Chondrites have compositions that are similar to the Sun, and represent the average composition of the solar system, thought to be close to the original composition of the solar nebula. 6 billion years ago. Some chondrites contain materials called calcium-aluminum inclusions, that may represent pre-solar system material.
