In the asteroid belt, there are several groups of different estimated ages. They orbit the Sun, and among them, the C-type asteroids are the most ancient.
The thickness of the asteroid belt is believed to be at around 1 AU. Most of them are located in the central asteroid belt between Mars and Jupiter. They are leftovers from the early solar system. FormationĪll asteroids are rocky remnants from 4.6 billion years ago. Since C-type asteroids are usually dark, much darker than other types of asteroids, except for D-types, they are also less detectable. Their proportions may be even higher than this. The C-type asteroid group holds together three other sub-groups of carbonaceous asteroids: B-type, F-type, and G-type.ĭistinguished by their typical low albedo due to their composition, C-type asteroids are mostly found in the outer edge of the asteroid belt, almost 3.5 AU away from the Sun.Īround 80% of the asteroids located there are of this kind, whereas 40% of asteroids at 2 AU from the Sun are C-type.This will happen when the Sun approaches the end of its life. One day, the entire asteroid belt will be gone.The average distance between asteroids is around 600.000 mi / 1 million km.Most C-type asteroids are located in the famous asteroid belt.Though they are among the most numerous, their low albedo makes them very difficult to observe.Most asteroids have irregular shapes similar to that of a potato.The total mass of all known asteroids constitutes around 4% of the Moon’s mass.The C-type asteroids have albedos typically in the 0.03 and 0.10 range.C-type asteroids share the same spectral classification as carbonaceous meteorites.They have a charcoal-like appearance due to their high concentration of carbon.C-type asteroids are among the most ancient celestial objects in our solar system.Though Ceres is classified as a G-type asteroid, it falls under the C-type group thus, the dwarf-asteroid-planet is the most massive asteroid of the C-class type.They are the most numerous asteroids in the Solar System.C-type asteroids are among the darkest celestial objects in color.C-type asteroids are the most common type of asteroids, forming around 75% of all known asteroids in the solar system.
