[3] Viola is a non-family asteroid of the main belt's background population when applying the Hierarchical Clustering Method to its proper orbital elements.
The family, named after 44 Nysa, is located near the Kirkwood gap (3:1 orbital resonance with Jupiter), a depleted zone that separates the central main belt.
[17] In the Tholen classification, Viola is a rare F-type asteroid, while in the SMASS taxonomy, it is classified as a common, carbonaceous C-type.
[15] A tentative period of 14.4 hours was measured by French amateur astronomer René Roy in January 2009, but later retracted from the LCDB (U=n.a.).
[6][7][8][9][10][11][12][13][14] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0415 and a diameter of 22.63 kilometers based on an absolute magnitude of 12.30.
