Carbon small body Carbon: These bodies are composed primarily of carbon, which is often hard packed. The core of these worlds may be a diamond, a block of carbon nanotube, or even a rare natural hyperdiamond. Small Body: The smallest independent orbital bodies that are not large enough to be shaped by gravity or clear their orbits. They tend to be oddly shaped and are often accompanied by other objects in orbit. These worlds may be habitable. The tiniest worlds are Class 1 small bodies with an average diameter ranging from 0.5km to Class 10, topping out at 700km. While small bodies are uncommon orbital bodies, they are common satellites.
