 In both the Tholen- and SMASS-like taxonomy of the Small Solar System Objects Spectroscopic Survey (S3OS2), "Lyka" is an X-type asteroid.In January 2005, a rotational lightcurve of "Lyka" was obtained from photometric observations by Matthieu Conjat.Lightcurve analysis gave a well-defined rotation period of hours with a low brightness variation of magnitude, indicative of a rather spherical shape ().
