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.
