58 Concordia

58 Concordia was discovered by German astronomer Robert Luther on March 24, 1860. At Luther's request the name was assigned by Karl Christian Bruhns of the University of Leipzig in honor of Concordia, the Roman goddess of harmony; sources treat this as a naming attribution rather than ascribing any mythological agency or narrative to the asteroid itself.

Classified as a C-type asteroid, 58 Concordia has a very dark, likely carbonaceous surface with spectral indications of hydrated minerals from aqueous alteration. Diameter estimates vary among sources; one cited value is about 69 2/3 miles (≈112 km), while other summaries present size data without a single uniform figure. It rotates with a sidereal period of 9.894541 hours and has two reported pole solutions: (15.3°±0.7°, −4.2°±2.6°) and (195.9°±1.0°, 4.8°±1.2°).

As documented in astronomical sources, 58 Concordia exhibits the physical and orbital behaviors of a main-belt minor planet: it orbits the Sun with a semimajor axis near 2.7 AU, a low eccentricity (~0.043), and an orbital period of approximately 4.44 years (around 4 years, 256 days). It belongs to the Nemesis family of asteroids. Sources do not attribute agency, intentions, or supernatural powers to the object.
