 "Tanina" is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method (HCM) by Nesvorný to its proper orbital elements.In the 1995 HCM-analysis by Zappalà, however, "Tanina" is a member of the Flora family (), a giant asteroid family and the largest family of stony asteroids in the main-belt.In the HCM-analysis by Milani and Knežević (AstDys), it is also a background asteroid as this analysis does not recognize the Flora asteroid clan.
