Primarily found in the asteroid belt between Mars and Jupiter, these rocky remnants are leftovers from the early solar system, believed to be composed of the primordial material that never coalesced into planets.

One of the defining characteristics of asteroids is their rocky composition, which distinguishes them from their icy counterparts, the comets. Asteroids are primarily made up of minerals and metals, including iron, nickel, and silicate, giving them a solid and often irregular shape. Their surfaces can vary significantly, with some displaying craters, grooves, and even mountains, while others appear smooth and featureless. The size of asteroids can also vary dramatically, ranging from a few meters to hundreds of kilometers in diameter. The largest known asteroid, Ceres, is classified as a dwarf planet and measures about 940 kilometers across.

Asteroids are categorized into different types based on their composition. The three main categories are C-type (carbonaceous), S-type (silicaceous), and M-type (metallic). C-type asteroids are the most common and are rich in carbon, making them dark and difficult to observe. S-type asteroids are composed primarily of silicate minerals and metals, giving them a brighter appearance. M-type asteroids are metallic and often contain significant amounts of iron and nickel, making them of particular interest for mining in the future.

In addition to their composition, asteroids exhibit unique orbits and can sometimes be found in resonance with the planets. Some have even been identified as potential Earth impactors, sparking interest in planetary defense strategies to mitigate any potential threat they may pose.
