Rhodia (minor planet designation: 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.[4] 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.[2] 437 Rhodia was originally a proposed fly-by target of interest for the Rosetta mission.[5]

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.[6] 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.[7]
