It was discovered on 22 October 1900, by German astronomer Max Wolf at the Heidelberg Observatory in southwest Germany.
[14][16] In April 2007, a rotational lightcurve of Saskia was obtained from photometric observations by French amateur astronomer Pierre Antonini.
Lightcurve analysis gave a well-defined rotation period of 7.348±0.001 hours with a brightness variation of 0.36 magnitude (U=3).
[12][14] In December 2016, an identical period with an amplitude of 0.28 magnitude was determined by Daniel Klinglesmith at Etscorn Campus Observatory (719), New Mexico (U=3-).
[8] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10 and derives a smaller diameter of 33.69 kilometers based on an absolute magnitude of 10.48.
