2730 Barks, provisional designation 1981 QH, is a carbonaceous

Edward Bowell at Anderson Mesa Station, Arizona, United States.[11] The asteroid was named after comic-book illustrator Carl Barks.[2]

Orbit and classification

Barks orbits the Sun in the central main-belt at a distance of 2.4–3.1 AU once every 4 years and 6 months (1,640 days). Its orbit has an eccentricity of 0.13 and an inclination of 6° with respect to the ecliptic.[1]

It was first identified as 1935 FQ at

Johannesburg Observatory in 1935. The body's observation arc begins with a precovery taken at Palomar Observatory in 1954, or 27 years prior to its official discovery observation at Anderson Mesa.[11]

Physical characteristics

In the

SMASS taxonomy, Barks is characterized as a carbonaceous C-type asteroid.[1]

Rotation period

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.162 and 0.415.[3][4][5][6]

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 24.30 kilometers with an absolute magnitude of 11.8.[7]

Naming

This minor planet was named for American cartoonist Carl Barks (1901–2000), best known for the fictional character Scrooge McDuck he created while working at Walt Disney in the late 1940s. In many of his stories, he described space exploration and adventure. Barks was one of the first to use the term "rubble pile asteroid".[2]

Peter Thomas, an assistant of

M.P.C. 7621).[12] A week later, Thomas informed Barks by mail about his initiative.[13]
