G-class asteroid

G-class asteroids are a taxonomic classification of asteroids characterized by a mean albedo of 0.09. Their spectral reflectivity is similar to the C-class asteroids but with a deeper absorption at wavelengths of 0.4 micrometers or shorter. Some G-class asteroids, like Ceres, may have water present as permafrost.1

Asteroids are remnants from the early formation of the solar system, with their orbits influenced by gravitational interactions with giant planets like Jupiter. Collisions between asteroids have led to their fragmentation and the formation of asteroid families, while solar radiation can alter the orbits of smaller asteroids.2
