Iclea is a large main belt asteroid with the minor planet designation, 286 Iclea. [4] It was discovered by Austrian astronomer Johann Palisa on 3 August 1889 in Vienna, and named for the heroine of Camille Flammarion's astronomical romance Uranie. [5] [6] This object is orbiting the Sun at a distance of 3.19 AU with a period of 5.711 years and an orbital eccentricity (ovalness) of 0.029. The orbital plane is tilted at an angle of 17.9° to the plane of the ecliptic. [1]
This asteroid has a classification of CX in the Tholen taxonomy, indicating a generally carbonaceous composition. [1] Infrared measurements indicate a cross-sectional diameter of approximately 94.3 km. [2] Photometric observations of this asteroid in 2001 provided a light curve that was used to derive a synodic rotation period of 15.365±0.002 hours with an amplitude of 0.15 magnitude. [3]
