3066 McFadden, provisional designation Шаблон:Mp, is a stony background asteroid from the central regions of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 1 March 1984, by American astronomer Edward Bowell at the Anderson Mesa Station near Tucson, Arizona. It was named for American planetary scientist Lucy-Ann McFadden.[1] The assumed S-type asteroid has a rotation period of 13.8 hours.[2]Шаблон:Efn

Orbit and classification

McFadden is a non-family asteroid from the main belt's background population.[3] It orbits the Sun in the central asteroid belt at a distance of 2.2–2.9 AU once every 4 years (1,466 days; semi-major axis of 2.53 AU). Its orbit has an eccentricity of 0.13 and an inclination of 16° with respect to the ecliptic.[4]

The asteroid was first observed as Шаблон:Mp at the Simeis Observatory in June 1933. The body's observation arc begins as Шаблон:Mp at Uccle Observatory in March 1936, or 48 years prior to its official discovery observation at Anderson Mesa.[1]

Naming

This minor planet was named after Lucy-Ann McFadden (born 1952), a planetary scientist at the University of Maryland at the time of naming. Her research included the similarities between the spectra of meteorites and near-Earth objects.[1] The official naming citation was published by the Minor Planet Center on 14 April 1987 (Шаблон:Small).[5]

Physical characteristics

McFadden is an assumed, stony S-type asteroid.[2]

Rotation period

In June 2005, a rotational lightcurve of McFadden was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory in Colorado. Lightcurve analysis gave a rotation period of 13.798 hours with a brightness amplitude of 0.13 magnitude (Шаблон:Small).[6]Шаблон:Efn

Diameter and albedo

According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, McFadden measures between 13.526 and 15.63 kilometers in diameter and its surface has an albedo between 0.240 and 0.363.[7][8][9][10][11]

The Collaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE data with an albedo of 0.2541 and a diameter of 14.90 kilometers based on an absolute magnitude of 11.24.[2][9]
