There are three major types of asteroids: C-Carbonaceous (comprised of ancient carbon silicates), S-Silicates (made of rocky silicates and iron), and M-Types (rich in metals, mostly nickel and ...

In the vast expanse of space, an estimated 1 million near-Earth objects (NEOs), also known as near-Earth asteroids, are constantly orbiting close to our planet. Every night, astronomers track NEOs ...

Asteroids are made of rock, metals and other elements. Some even contain water, astronomers say. Asteroids that are mostly stone sometimes are more like loose piles of rubble.

Asteroids made of "rubble" might be very, very hard to destroy, astronomers say A new study of rubble pile asteroids means we may have to rethink planetary defense strategies ...

Some asteroids like Ceres, are so large that they are classified as dwarf planets. Asteroids are usually grouped into three main types based on what they are made of: C-type, S-type and M-type.

Most of the asteroids we see orbiting the Sun are the dark-coloured C-types. Based on their spectrum, C-types seem very similar in makeup to a kind of meteorite called carbonaceous chondrites.
