Water Content of Space Bodies In general, are carbonaceous chondrites (CC) or comets more water rich?


I know that evidence has suggested that both CC and comets are partly composed of water, but which body is generally more water rich?
I compared C type asteroids and comets for this question. C type asteroids have around 30% of empty space, meaning that that much space can be for water.

Comets have around 40% of empty space.

Obviously, just because they have more empty space does not mean they have more water. However, evidence for water on Earth originally comes from comets. Not only that, but comets are occasionally balls of ice with some rock. Asteroids are known for being just rocks, and only have a limited amount of water.

In conclusion, comets are more water rich.

Hope that helps...?
