[3][8] It orbits the Sun in the outer main-belt at a distance of 2.6–3.2 AU once every 4 years and 12 months (1,817 days).

[9] A rotational lightcurve of Lundmarka was obtained from photometric observations made at the Australian Oakley Southern Sky Observatory (E09) in September 2014.

Using lightcurve inversion and convex shape models, as well as distributed computing power and the help of individual volunteers, a period of 6.25033±0.00001 hours was derived from the database's sparse-in-time photometry data (U=n.a.).

[3] This minor planet was named in memory of Swedish astronomer Knut Lundmark (1889–1958), who was the head of the Lund Observatory.

He thoroughly analyzed galaxies and globular clusters, and pioneered in measuring galactic distances and absolute stellar magnitudes.
