[2] Villigera is a Mars-crossing asteroid, a dynamically unstable group between the main belt and the near-Earth populations, crossing the orbit of Mars at 1.666 AU.

[1] In October 2001, a first rotational lightcurve of Villigera was obtained by astronomer Robert Koff at Thornton Observatory (713) in Colorado.

[6][a] Photometric observations by astronomers René Roy, Raoul Behrend and Pierre Antonini in February 2006, gave a concurring period of 7.834 hours and an amplitude of 0.36 magnitude (U=3).

[8] In 2016, a modeled lightcurves using photometric data from various sources, rendered an identical period of 7.830 and a spin axis of (3.0°, 63°) in ecliptic coordinates.

This minor planet was named in honour of Swiss astronomer Walther Villiger (1872–1938), who himself discovered the main-belt asteroid 428 Monachia at Munich in 1897.
