    754 Malabar is a minor planet orbiting the Sun. It was discovered in 1906 by German astronomer August Kopff from Heidelberg, and was named in honor of a Dutch-German solar eclipse expedition to Christmas Island in 1922. Malabar is the name of a city and mountain in Indonesia. [5] This object is orbiting at a distance of 2.99  AU from the Sun with a period of 5.16 years and an eccentricity (ovalness) of 0.048. Its orbital plane is inclined at an angle of 24.6° to the plane of the ecliptic. [3]

    Photometric measurements of this asteroid made in 2003 resulted in a light curve showing a rotation period of 11.740±0.005 h and a brightness variation of 0.45±0.03 in magnitude. [5] This is a Ch-class asteroid in the Bus asteroid taxonomy, showing a broad absorption band in its carbonaceous spectrum near a wavelength of 0.7 μm. This feature is interpreted as due to iron-bearing phyllosilicates on the surface. 754 Malabar spans a girth of 102.8 km. [4] Between 2002 and 2022, 754 Malabar has been observed to occult sixteen stars.

    Klymene is a large, dark Themistian asteroid that was discovered by J. C. Watson on September 13, 1868, and named after one of the many Clymenes in Greek mythology. 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.
