19367 Pink Floyd (provisional designation1997 XW3) is a dark backgroundasteroid from the inner regions of theasteroid belt, approximately 7 kilometers in diameter. It was discovered on 3 December 1997, by European astronomers of theODAS survey at theCERGA Observatory near Caussols, France.[5] The asteroid was named after the English rock bandPink Floyd.[2]
Pink Floyd is a non-family asteroid from thebackground population.[3] It orbits the Sun in theinner main-belt at a distance of 2.0–2.8 AU once every 3 years and 10 months (1,397 days). Its orbit has aneccentricity of 0.16 and aninclination of 4° with respect to theecliptic.[1]
The asteroid was first identified as1985 UZ2 at the discovering Caussols Observatory in October 1985. Itsobservation arc begins 43 years prior to its official discovery observation, with aprecovery taken by theDigitized Sky Survey atPalomar Observatory in July 1954.[5]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, Pink Floyd measures 6.652 kilometers in diameter and its surface has a lowalbedo of 0.048.[4] An albedo near 0.05 is typical for carbonaceousC-type asteroids, which are the dominanttype in the outer region of the main belt, but rather unusual in the inner parts. Pink Floyd has anabsolute magnitude of 14.6.[1]
As of 2017, no rotationallightcurve of Pink Floyd has been obtained from photometric observations. The asteroid'srotation period,spin axis and shape remain unknown.[1][6]
Thisminor planet was named after the English rock bandPink Floyd, which released several astronomically themed songs such as "Interstellar Overdrive" and "Astronomy Domine". The band's albumThe Dark Side of the Moon (1973) became one of thebest-selling records of all time.[2]
The official naming citation was published by theMinor Planet Center on 6 August 2003 (M.P.C. 49281).[7]
