325 Heidelberga is a large main belt asteroid that was discovered by German astronomer Max Wolf on 4 March 1892 in Heidelberg. It is orbiting the Sun at a distance of with an eccentricity (oval shape) of 0.159. The orbital plane is inclined at an angle of 8.55° to the ecliptic.
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. A weak feature in the near infrared spectrum indicates the presence of low-iron orthopyroxene on the asteroid surface.
