120375 Kugel, provisional designation : 2005 PB6, is a background asteroid from the inner regions of the asteroid belt, approximately 1 kilometer (0.6 miles) in diameter. It was discovered on 10 August 2005, by French amateur astronomer Claudine Rinner at her Ottmarsheim Observatory ( 224 ) in France. [1] The stony S/Q-type asteroid in the region of the Florian clan has a tentative rotation period of 6.9 hours. [5] It was named after French astronomer François Kugel. [1]
Kugel is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. [3] [4] Based on osculating Keplerian orbital elements, the asteroid has also been considered a member of the Flora family ( 402 ), a giant asteroid clan and the largest family of stony asteroids in the main belt. [5]
It orbits the Sun in the inner asteroid belt at a distance of 1.8–2.8 AU once every 3 years and 6 months (1,289 days; semi-major axis of 2.32 AU). Its orbit has an eccentricity of 0.22 and an inclination of 3° with respect to the ecliptic. [2] The body's observation arc begins with its first observation as 1998 SM108 at Lincoln Laboratory ETS in September 1998, nearly 7 years prior to its official discovery observation at Ottmarsheim. [1]
This minor planet was named after French amateur astronomer François Kugel (born 1959), an active observer of comets and a collaborator of the discoverer. He has founded the Chante-Perdrix Observatory ( A77 ) in 2005. [1] The official naming citation was published by the Minor Planet Center on 6 August 2009 ( M.P.C. 66728). [8]
In the SDSS-based taxonomy, Kugel has an SQ-type that transitions between the common S-type and less common Q-type asteroids. [7]
In August 2012, a rotational lightcurve of Kugel was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a tentative rotation period of 6.923±0.0085 hours with a weak brightness amplitude of 0.09 magnitude ( U=1 ). [6] As of 2021, no secure period has been obtained. [5]
Kugel has not been observed by any of the space-based surveys such as the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the Akari satellite or IRAS. The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora the parent body of the Flora family – and calculates a diameter of 1.05 kilometers based on an absolute magnitude of 17.07.
