2348 Michkovitch, provisional designation Template:Mp, is a presumed carbonaceous Erigone asteroid from the inner regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered by Serbian astronomer Milorad Protić at Belgrade Observatory on 10 January 1939.[1] The asteroid was named after Serbian astronomer Vojislav Mišković.[2]
Orbit and classification
Michkovitch is a member of the Erigone family, named after 163 Erigone, its largest member and namesake.[3] It is a rather young cluster (170–280 My) of dark carbonaceous asteroids in the inner asteroid belt, which otherwise consists mostly of stony asteroids.[4]
It orbits the Sun in the inner main-belt at a distance of 2.0–2.8 AU once every 3 years and 9 months (1,356 days). Its orbit has an eccentricity of 0.17 and an inclination of 5° with respect to the ecliptic.[5] No precoveries were taken. The asteroid's observation arc starts 15 days after its official discovery with the first used observation taken at the Royal Observatory of Belgium.[1]
Naming
This minor planet was named by the discoverer after his professor Vojislav Mišković (1892–1976), first director of the new Belgrade Observatory and founder of the Astronomical Institute at SANU.[2] The official naming citation was published by the Minor Planet Center on 7 March 1985 (M.P.C. 9477Script error: No such module "Check for unknown parameters".).[6]
Physical characteristics
Rotation period
A 2011-published rotational lightcurve of Michkovitch was obtained from photometric observations by Australian amateur astronomer David Higgins. Lightcurve analysis gave a longer-than average rotation period of 28 hours with a brightness variation of 0.12 in magnitude (U=2Script error: No such module "Check for unknown parameters".).Template:Efn
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Michkovitch measures 4.6 and 4.8 kilometers in diameter and its surface has an outstanding albedo of 0.84 and 0.92, respectively.[7][8]
The Collaborative Asteroid Lightcurve Link strongly disagrees with the result obtained by the space-based observatory and assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a much larger diameter of 15.4 kilometers, as the lower the body's albedo (reflectivity), the larger its diameter at a constant absolute magnitude (brightness).[3]
