1652 Hergé, provisional designation1953 PA, is a stony Florianasteroid from the inner regions of theasteroid belt, approximately 9 kilometers in diameter. It was discovered on 9 August 1953, by Belgian astronomerSylvain Arend at theRoyal Observatory of Belgium in Uccle, Belgium.[8] It was later named after Belgian cartoonistHergé.[2]
Hergé is a member of theFlora family, one of the largest families ofstony asteroids. It orbits the Sun in theinner main-belt at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,234 days). Its orbit has aneccentricity of 0.15 and aninclination of 3° with respect to theecliptic.[1] It was first identified as1933 UE1 atHeidelberg Observatory in 1933, extending the body'sobservation arc by 20 years prior to its official discovery observation.[8]
Hergé has been characterized as a commonS-type asteroid byPan-STARRS photometric survey.[7]
AstronomerPetr Pravec obtained a rotationallightcurve ofHergé from photometric observations taken atOndřejov Observatory in September 2014.[b] It gave arotation period of 16.36 hours with a brightness amplitude of 0.42magnitude (U=3-).[a]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Hergé measures between 8.68 and 8.95 kilometers in diameter, and its surface has analbedo between 0.116 and 0.308.[4][5][6] TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 9.41 kilometers with anabsolute magnitude of 12.54.[3]
Thisminor planet was named in honor of Belgian cartoonistGeorges Remi, better known under his pseudonym Hergé. He is considered to be the father of the fictionalAdventures of Tintin, one of the most popular European comics of the 20th century, and creator of its hero,Tintin, in 1929.[2] The asteroid1683 Castafiore was also named after the comic-strip characterBianca Castafiore from the series. The approved naming citation was published by theMinor Planet Center on 8 April 1982 (M.P.C. 6831).[9]
