C-type asteroid
The largest unequivocally C-type asteroid is 10 Hygiea, although the SMASS classification places the largest asteroid, 1 Ceres, here as well, because that scheme lacks a G-type.
2001 AV43
is a member of the dynamical Apollo group, which are Earth-crossing asteroids. Apollo asteroids are the largest subgroup of near-Earth objects. Unlike many Apollo asteroids, this asteroid is not a Mars-crosser, as its aphelion is smaller than the orbit of the Red Planet at 1.66 AU.
