 Asteroid spectral types

Asteroid spectral types are classifications of asteroids based on their reflectance spectra, which is the way they reflect light across different wavelengths. These spectral types help astronomers understand the composition, surface properties, and origins of asteroids. Different spectral types correspond to different mineralogical and chemical compositions. The most commonly used spectral classifications for asteroids include: 1. **C-type (Carbonaceous)**: These are the most common type, making up about 75% of all known asteroids.
