217 Eudora
Eudora is a large Main belt asteroid. It was discovered by French astronomer J. Coggia on August 30, 1880, in Marseilles, France. It was his fourth asteroid discovery and is named after Eudora, a Hyad in Greek mythology.
It probably has a composition similar to carbonaceous chondrites. In 2007, a study showed it rotates every 25.253 ± 0.003 hours, based on lightcurve data. A light curve generated from photometric observations at Pulkovo Observatory, give a matching rotation period of 25.253 ± 0.002 hours and a brightness variation of 0.22 ± 0.04 in magnitude.
