10241 Miličević, provisional designation 1999 AU6, is a carbonaceous Themistian asteroid from the outer regions of the asteroid belt, approximately 11 kilometers (6.8 miles) in diameter. It was discovered on 9 January 1999, by Croatian astronomer Korado Korlević at the Višnjan Observatory in Croatia. The C-type asteroid has a short rotation period of 3.87 hours and was named after hermit and amateur astronomer Don Nikola Miličević.[1][3]

## Orbit and classification

Miličević is a Themistian asteroid that belongs to the Themis family (602),[4] a very large family of carbonaceous asteroids, named after 24 Themis.[9] It orbits the Sun in the outer main-belt at a distance of 2.6–3.5 AU once every 5 years and 4 months (1,944 days; semi-major axis of 3.05 AU). Its orbit has an eccentricity of 0.16 and an inclination of 2° with respect to the ecliptic.[2]

The body's observation arc begins with its first observation at Palomar Observatory in October 1981, more than 17 years prior to its official discovery observation at Višnjan.[1]

## Physical characteristics

Based on its classification to the Themis family and on observations conducted by the Pan-STARRS survey, Miličević is a carbonaceous C-type asteroid.[3][8]

### Rotation period

In December 2014, a rotational lightcurve of Miličević was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a short rotation period of 3.87 hours with a brightness amplitude of 0.34 magnitude ({{{1}}}).[3][7]

### Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Miličević measures 10.882 kilometers in diameter and its surface has an albedo of 0.065,[5][6] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous asteroid of 0.057 and calculates a diameter of 8.39 kilometers based on an absolute magnitude of 14.11.[3]

## Naming

This minor planet was named after Don Nikola Miličević (1887–1963), Croatian amateur astronomer and last administrator of Blaca hermitage. The Hermitage is a UNESCO World Heritage Site located on the Brač island in Croatia.[1] The official naming citation was published by the Minor Planet Center on 15 December 2005 (M.P.C. 55720).[10]
