What is the most common type of rock on asteroids?

The most common type of rock found on asteroids is known as chondrite. Chondrites are stony (non-metallic) meteorites that contain small spherical chondrules composed of minerals such as olivine and pyroxene. These chondrules are believed to have formed from the solar nebula before the asteroids themselves.

Chondrites make up over 85% of all meteorites that fall to Earth, and are believed to represent the most primitive material in the Solar System. They are typically composed of various minerals, including silicates and oxides.

It is important to study asteroids and their composition, as they provide a window into the early history of our Solar System. By analyzing the materials that make up asteroids, we can better understand how the planets and other celestial bodies formed and evolved over time.
