7553 Buie (/ˈbuːiː/), provisional designation 1981 FG, is a Nysa asteroid from the inner regions of the asteroid belt, approximately 3.5 kilometers (2.2 miles) in diameter. It was discovered on 30 March 1981, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona.[1] The stony S-type asteroid has a rotation period 4.2 hours an possibly an elongated shape.[7] It was named after American astronomer Marc Buie.[2]
Buie is a core member of the Nysa family (405),[4] also known as the Herta family,[11] located within the Nysa–Polana complex. It is one of the largest asteroid families of the asteroid belt and named after 44 Nysa.[12]
It orbits the Sun in the inner main-belt at a distance of 2.0–2.7 AU once every 3 years and 8 months (1,351 days; semi-major axis of 2.39 AU). Its orbit has an eccentricity of 0.15 and an inclination of 3° with respect to the ecliptic.[3] A first precovery was taken at the Palomar Observatory in December 1950, extending the asteroid's observation arc by 31 years prior to its discovery.[1]
Naming
This minor planet was named in honor of American Marc William Buie (born 1958), an astronomer at the discovering Lowell Observatory and a prolific discoverer of minor planets including several trans-Neptunian objects. His contributions to planetary astronomy also include research on the moons of Pluto and the development of widely used astronomical software.[2] The official naming citation was published by the Minor Planet Center on 28 July 1999 (M.P.C. 35486).[13]
