7553 Buie (), 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]
Orbit and classification [ edit ]
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]
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]
Physical characteristics [ edit ]
Buie has been characterized as a stony S-type asteroid by PanSTARRS photometric survey.[7] [9] It is also an S-type in the SDSS -based taxonomy,[10] and agrees with the overall spectral type of the Nysa family .
Rotation period [ edit ]
In September 2012, a rotational lightcurve of Buie was obtained from photometric observations made at the Palomar Transient Factory , California. In the R-band, it gave a rotation period of 4.2418± 0.0071 hours with a brightness variation of 0.51 magnitude , while in the SG-Band the period was 4.2453± 0. hours with an amplitude of 0.53 magnitude (U=2/2 ).[7] [8] A high brightness variation typically indicates a non-spherical shape.
Diameter and albedo [ edit ]
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , Buie measures 3.4 kilometers in diameter and its surface has an albedo of 0.259,[5] [6] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.92 kilometers using an absolute magnitude of 14.4.[7]
