325 Heidelberga is a large Main belt asteroid that was discovered by German astronomer Max Wolf on March 4, 1892 in Heidelberg.

Based upon its spectrum, 325 Heidelberga is classified as an M-type asteroid. No absorption features have been detected with certainty, indicating it most likely has a nickel-iron or enstatite chondrite composition.[2]
