It orbits the Sun in the inner main-belt at a distance of 1.9–2.6 AU once every 3 years and 5 months (1,234 days).

[8] Hergé has been characterized as a common S-type asteroid by Pan-STARRS photometric survey.

[7] Astronomer Petr Pravec obtained a rotational lightcurve of Hergé from photometric observations taken at Ondřejov Observatory in September 2014.

[4][5][6] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 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.

[3] This minor planet was named in honor of Belgian cartoonist Georges Remi, better known under his pseudonym Hergé.
