354 Eleonora is a large stony main-belt asteroid that was discovered by the French astronomer Auguste Charlois on January 17 1893 in Nice.Photometric observations of this asteroid gave a light curve with a period of 13.623 hours. The data was used to construct a model for the asteroid revealing it to be a regular-shaped object spinning about a pole with ecliptic coordinates (β λ) = (+20° 356°) although this is with an accuracy of only ±10°.
