C-Type Asteroids and Carbonaceous Chondrite Meteorites I was just wondering, what is the relationship between C-type asteroids and carbonaceous chondrite (CC) meteorites? Do CC meteorites come from C-type asteroids?
The difference between asteroids, comets and meteors is discussed in What is the difference between asteroids, comets and meteors?

Some groupings of asteroids have been correlated with meteorite types:


  C-type – Carbonaceous chondrite meteorites
  S-type – Stony meteorites
  M-type – Iron meteorites
  V-type – HED meteorites


The S- and C-type asteroid classifications originate from the taxonomy proposed by David Tholen.

Meteors are generally considered to be asteroids which enter Earth's atmosphere. 
Meteorites are meteor remnants which reach the ground. So essentially, carbonaceous chondrite meteor(ite)s start out as C-type asteroids; they're made of the same stuff.
