'''1652 Hergé''', provisional designation {{mp|1953 PA}}, is a stony Florian [[asteroid]] from the inner regions of the [[asteroid belt]], approximately 9 kilometers in diameter. It was discovered on 9 August 1953, by Belgian astronomer [[Sylvain Arend]] at the [[Royal Observatory of Belgium]] in Uccle, Belgium.<ref name="MPC-Herge" /> It was later named after Belgian cartoonist [[Hergé]].<ref name="springer" />

== Orbit and classification ==

''Hergé'' is a member of the [[Flora family]], one of the largest families of [[S-type asteroid|stony asteroids]]. It orbits the Sun in the [[Kirkwood gap|inner]] main-belt at a distance of 1.9–2.6&nbsp;[[Astronomical unit|AU]] once every 3 years and 5 months (1,234 days). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.15 and an [[orbital inclination|inclination]] of 3[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> It was first identified as {{mp|1933 UE|1}} at [[Heidelberg Observatory]] in 1933, extending the body's [[observation arc]] by 20 years prior to its official discovery observation.<ref name="MPC-Herge" />

== Physical characteristics ==

''Hergé'' has been characterized as a common [[S-type asteroid]] by [[Pan-STARRS]] photometric survey.<ref name="Veres-2015" />

=== Rotation period ===

Astronomer [[Petr Pravec]] obtained a rotational [[lightcurve]] of ''Hergé'' from photometric observations taken at [[Ondřejov Observatory]] in September 2014.{{efn|name=Screenshot-Lightcurve}} It gave a [[rotation period]] of 16.36 hours with a brightness amplitude of 0.42 [[Magnitude (astronomy)|magnitude]] ({{small|[[LCDB quality code|U=3-]]}}).{{efn|name=LCDB-Pravec-2014}}

=== Diameter and albedo ===

According to the survey carried out by NASA's [[Wide-field Infrared Survey Explorer]] with its subsequent [[NEOWISE]] mission, ''Hergé'' measures between 8.68 and 8.95 kilometers in diameter, and its surface has an [[astronomical albedo|albedo]] between 0.116 and 0.308.<ref name="Masiero-2012" /><ref name="WISE" /><ref name="Masiero-2014" /> The ''Collaborative Asteroid Lightcurve Link'' assumes an albedo of 0.24 – derived from [[8&nbsp;Flora]], the largest member and namesake of this orbital family – and calculates a diameter of 9.41 kilometers with an [[absolute magnitude]] of 12.54.<ref name="lcdb" />

== Naming ==

This [[minor planet]] was named in honor of Belgian cartoonist [[Georges Remi]], better known under his pseudonym Hergé. He is considered to be the father of the fictional ''[[Adventures of Tintin]]'', one of the most popular European comics of the 20th century, and creator of its hero, ''[[Tintin (character)|Tintin]]'', in 1929.<ref name="springer" /> The asteroid [[1683 Castafiore]] was also named after the comic-strip character ''[[Bianca Castafiore]]'' from the series. The approved naming citation was published by the [[Minor Planet Center]] on 8 April 1982 ({{small|[[Minor Planet Circulars|M.P.C.]] 6831}}).<ref name="MPC-Circulars-Archive" />
