437 Rhodia is a Main belt asteroid that was discovered by French astronomer Auguste Charlois on 16 July 1898 in Nice. It was named after one of the Oceanid nymphs of Greek mythology. This asteroid is orbiting the Sun at a distance of 2.39 AU with a period of 3.69 years and an eccentricity (ovalness) of 0.25. The orbital plane is tilted at an angle of 7.3° to the plane of the ecliptic. 437 Rhodia was originally a proposed fly-by target of interest for the Rosetta mission.

Analysis of the bimodal light curve generated using photometric data show a lengthy rotation period of 433.2 ± 0.5 hours (18.05 ± 0.02 days) with a brightness variation of 0.35±0.05 in magnitude. It also appears to be tumbling. 437 Rhodia is classified as an E-type asteroid with a diameter of approximately 13 km. This object has the highest albedo in the IRAS dataset, with a value of 0.70±0.08.
