334 Chicago is a very large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
It was discovered by Max Wolf on August 23, 1892, in Heidelberg.
During 1999, the asteroid was observed occulting a star. The resulting chords provided a cross-section diameter estimate of 174.1 km.[3]
