[9] Lidiya has been characterized as a stony S-type asteroid by PanSTARRS photometric survey.
[8] In December 2012, a fragmentary rotational lightcurve of Lidiya was obtained from photometric observations at the Altimira Observatory (G76) in California.
Lightcurve analysis gave a rotation period of 710 hours with a brightness amplitude of 0.60 magnitude (U=1).
[5][6] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.23 – derived from 25 Phocaea, the Phocaea family's largest member and namesake – and calculates a diameter of 7.99 kilometers based on an absolute magnitude of 12.7.
