Inner, main and outer asteroid belt.
The belt asteroids tend to be carbonaceous in the inner belt with some silicate, the main belt is mostly silicate with some mixed (silicon with iron), outer are mostly nickel-iron.
The overall mass is unimpressive, about 1% of the Moon's
From recent observations of Vesta, apparently some large asteroids are differentiated
No Trojan has been examined close up, probably mostly mixed or nickel-iron.
Earth crossers are mostly from the inner or main belt
