19367 Pink Floyd ( provisional designation 1997 XW3) is a dark background asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 3 December 1997, by European astronomers of the ODAS survey at the CERGA Observatory near Caussols, France. [5] The asteroid was named after the English rock band Pink Floyd. [2]

Orbit and classification

Pink Floyd is a non- family asteroid from the background population. [3] It orbits the Sun in the inner main-belt at a distance of 2.0–2.8  AU once every 3 years and 10 months (1,397 days). Its orbit has an eccentricity of 0.16 and an inclination of 4 ° with respect to the ecliptic. [1]

The asteroid was first identified as 1985 UZ2 at the discovering Caussols Observatory in October 1985. Its observation arc begins 43 years prior to its official discovery observation, with a precovery taken by the Digitized Sky Survey at Palomar Observatory in July 1954. [5]

Physical characteristics

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Pink Floyd measures 6.652 kilometers in diameter and its surface has a low albedo of 0.048. [4] An albedo near 0.05 is typical for carbonaceous C-type asteroids, which are the dominant type in the outer region of the main belt, but rather unusual in the inner parts. Pink Floyd has an absolute magnitude of 14.6. [1]

Rotation period

As of 2017, no rotational lightcurve of Pink Floyd has been obtained from photometric observations. The asteroid's rotation period, spin axis and shape remain unknown. [1] [6]

Naming

This minor planet was named after the English rock band Pink Floyd, which released several astronomically themed songs such as " Interstellar Overdrive" and " Astronomy Domine". The band's album The Dark Side of the Moon (1973) became one of the best-selling records of all time. [2]

The official naming citation was published by the Minor Planet Center on 6 August 2003 ( M.P.C. 49281). [7]
