C. Watson on September 13, 1868, and named after one of the many Clymenes in Greek mythology.Dictionary of minor planet names 25 2003 International Astronomical Union. Springer It is orbiting the Sun with a period of 5.60 years and an eccentricity of 0.16. The orbital plane is inclined by 2.8° to the plane of the ecliptic. It is classified as a C-type asteroid, indicating it probably has a carbonaceous composition. The spectra indicates the presence of aqueous-altered minerals on the surface based upon a sharp feature at a wavelength of 3 μm, and, as of 2015, is the only member of the Themis family found to show this absorption. Based upon measurements made using adaptive optics at the W. M. Keck Observatory, this object may have a bi-lobed shape with a length of 163 ± 3 km and width of 103 ± 5 km, for an average dimension of 133 km. This asteroid is located near the region of the Themis family but itself considered a background asteroid using HCM-analysis. It is listed as a member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter. 104 Klymene has been observed to occult 6 stars between 2009 and 2023.
