'''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 of September 21, 1922|solar eclipse]] expedition to [[Christmas Island]] in 1922. Malabar is the name of a [[Malabar, Indonesia|city]] and [[Mount Malabar|mountain]] in Indonesia.<ref name=Stephens2003/> This object is orbiting at a distance of {{val|2.99|ul=AU}} from the Sun with a [[orbital period|period]] of {{convert|1885.1|days|years|2|disp=out|abbr=off}} and an [[orbital eccentricity|eccentricity]] (ovalness) of 0.048. Its [[orbital plane]] is inclined at an angle of 24.6° to the [[plane of the ecliptic]].<ref name="jpldata"/>
[[Photometry (astronomy)|Photometric]] measurements of this asteroid made in 2003 resulted in a [[light curve]] showing a [[rotation period]] of {{val|11.740|0.005|u=hours}} and a brightness variation of {{val|0.45|0.03}} in magnitude.<ref name=Stephens2003/> This is a [[C-type asteroid|Ch-class asteroid]] in the [[Bus–DeMeo classification|Bus asteroid taxonomy]], showing a broad absorption band in its [[carbon]]aceous spectrum near a wavelength of 0.7&nbsp;μm. This feature is interpreted as due to iron-bearing [[phyllosilicate]]s on the surface. 754 Malabar spans a girth of 102.8&nbsp;km.<ref name=Rivkin_et_al_2015/>  Between 2002 and 2022, 754 Malabar has been observed to [[occultation|occult]] sixteen stars.
