Шаблон:Mp is a rare-type asteroid from the inner regions of the asteroid belt, classified as Mars-crosser and exceptionally slow rotator, approximately 4 kilometers in diameter. It was discovered on 16 March 1999, by Croatian astronomers Korado Korlević and Mario Jurić at Višnjan Observatory in Croatia.[1]
Orbit and classification
Шаблон:Mp orbits the Sun at a distance of 1.7–3.0 AU once every 3 years and 7 months (1,309 days). Its orbit has an eccentricity of 0.29 and an inclination of 12° with respect to the ecliptic.[2] A first precovery was taken at Steward Observatory in 1992, extending the body's observation arc by 7 years prior to its official discovery observation.[1]
Physical characteristics
SDSS photometry characterized Шаблон:Mp as a rare and reddish L-type, which belong to the larger complex of stony asteroids.[3]
Slow rotator and tumbler
In September 2014, American astronomer Robert Stephens obtained a rotational lightcurve from photometric observations taken at the Center for Solar System Studies (CS3, Шаблон:Small) in California.Шаблон:Efn It gave an exceptionally long rotation period of Шаблон:Val hours with a brightness amplitude of 0.55 magnitude (Шаблон:Small), which makes it one of the slowest rotators known to exist. It is also a suspected tumbling asteroid, which show a non-principal axis rotation.[4]
Diameter and albedo
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Шаблон:Mp measures 3.395 and 4.17 kilometers in diameter and its surface has an albedo of 0.287 and 0.176, respectively.[5] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.92 kilometers with an absolute magnitude of 14.4.[6]
Numbering and naming
This minor planet was numbered by the Minor Planet Center on 28 March 2002.[7] As of 2018, it has not been named.[1]
