    Eurykleia (minor planet designation: 195 Eurykleia) is a fairly large main belt asteroid. It was discovered by the Austrian astronomer Johann Palisa on April 19, 1879, and named after Euryclea, the wet-nurse of Odysseus in The Odyssey .

    This body is orbiting the Sun with a period of 4.88 years and a low eccentricity (ovalness) of 0.04. The orbital plane is inclined by 7° from the plane of the ecliptic. It is spinning with a rotation period of 16.5 hours and varies in brightness with an amplitude of 0.24 magnitude. The cross-section diameter of this body is 43 km. The asteroid has a taxonomic type of Ch in the SMASS classification, [3] which indicates it has a dark surface with a primitive carbonaceous composition.

    195 Eurykleia has been observed to occult stars twice, once in 2011 and again in 2021.

    796 Sarita is a minor planet orbiting the Sun. It was discovered 15 October 1914 by German astronomer Karl W. Reinmuth. This is a main belt that is orbiting at a radius of 2.63 AU with a period of 4.28 yr and an eccentricity (ovalness) of 0.32. The orbital plane is inclined at an angle of 19.052° from the plane of the ecliptic. Tholen (1989) initially classified it as type XD, although later authors treated it as an M-class body. The object's visual albedo is considered characteristic of the latter type. It has a significantly higher radar albedo than most main belt objects, which also suggests a higher metallic content.
