Concordia (minor planet designation: 58 Concordia) is a fairly large main-belt asteroid that is orbiting the Sun with a period of 4.44 years, a semimajor axis of 2.7 AU, and a low eccentricity of 0.043. It is classified as a C-type asteroid, meaning that its surface is very dark and it is likely carbonaceous in composition. The surface spectra displays indications of hydrated minerals created through aqueous alteration.[5] The object is rotating with a sidereal period of 9.894541 h and pole orientations of (15.3°±0.7°, −4.2°±2.6°) and (195.9°±1.0°, 4.8°±1.2°).[6] It belongs to the Hungaria family of asteroids and has a satellite with an orbital period of 14.29 h.[3][dubious ]
