754 Malabar

Minor planet orbiting the sun

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.
