120375 Kugel, provisional designation: Шаблон:Mp, is a background asteroid from the inner regions of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 10 August 2005, by French amateur astronomer Claudine Rinner at her Ottmarsheim Observatory Шаблон:Obscode 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.[2] It was named after French astronomer François Kugel.[1]

Orbit and classification

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 (Шаблон:Small), a giant asteroid clan and the largest family of stony asteroids in the main belt.[2]

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.[5] The body's observation arc begins with its first observation as Шаблон:Mp at Lincoln Laboratory ETS in September 1998, nearly 7 years prior to its official discovery observation at Ottmarsheim.[1]

Naming

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 Шаблон:Obscode in 2005.[1] The official Шаблон:MoMP was published by the Minor Planet Center on 6 August 2009 (Шаблон:Small).[6]

Physical characteristics

In the SDSS-based taxonomy, Kugel has an SQ-type that transitions between the common S-type and less common Q-type asteroids.[7]

Rotation period

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 Шаблон:Val hours with a weak brightness amplitude of 0.09 magnitude (Шаблон:Small).[8] As of 2021, no secure period has been obtained.[2]

Diameter and albedo

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.[2]
