1652 Hergé, provisional designation 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.
Hergé is a S-type asteroid and member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,234 days). Its orbit has an eccentricity of 0.15 and an inclination of 3° with respect to the ecliptic.of 1.9–2.6 AU once every 3.38 years (1,233 days). Its orbit shows an eccentricity of 0.15 and is tilted by 3 degrees to the plane of the ecliptic. The was first identified as 1933 UE1 at Heidelberg Observatory in 1933, extending the body's observation arc by 20 years prior to its official discovery observation.
In September 2014, astronomer Petr Pravec obtained a rotational light-curve of Hergé from photometric observations taken at Ondřejov Observatory. It gave a rotation period of 16.36 hours with a brightness amplitude of 0.42 magnitude (U=3-).
