[12] The X-type asteroid (Xk) has a rotation period of 21.2 hours and measures approximately 18 kilometers (11 miles) in diameter.

[12] This minor planet was named after the vast geographic region of Siberia in North Asia, approximately 13.1 million square kilometres (5,100,000 sq mi) in area.

Lightcurve analysis gave a rotation period of 21.15 hours with a brightness amplitude of 0.45 magnitude, indicating a non-spherical shape (U=2).

[6][7][8][9][10] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1227 and a diameter of 18.16 kilometers based on an absolute magnitude of 11.6.

[4] 1094 Siberia is mentioned briefly in John Varley's science fiction novel Rolling Thunder, where it is described as "an escape-proof prison" of the Republic of Mars.
