[3] Located in or near the region of the Eunomia family,[11] Parysatis is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.
[4] In November 2006, a rotational lightcurve of Parysatis was obtained from photometric observations by Serbian astronomer Vladimir Benishek at Belgrade Observatory.
[10][11] The result supersedes other period determinations of (5.49±0.01 h) by Marcos Florczak in 1996,[12] (5.928±0.006 h) by Laurent Bernasconi in 2003,[13] and (5.933±0.001 h) by Michael Fleenor in 2006,[14] and by Andy Monson in 2011 (U=2/3−/3−/2).
[11] In April 2017, another lightcurve with a well-defined period of 5.931±0.003 hours and an amplitude of 0.23±0.03 magnitude was obtained by the Spanish group of asteroid observers, OBAS (U=3).
[7][8][9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1392 and a diameter of 44.65 kilometers with an absolute magnitude of 9.51.
