160 Una is a fairly large and dark, primitive Main belt asteroid that was discovered by German-American astronomer C. H. F. Peters on February 20, 1876, in Clinton, New York. It is named after a character in Edmund Spenser's epic poem The Faerie Queene (1590).
In the Tholen classification system it is categorized as a CX-type, while the Bus asteroid taxonomy system lists it as an Xk asteroid. Photometric observations of this asteroid made at the Torino Observatory in Italy during 1990–1991 were used to determine a synodic rotation period of 5.61 ± 0.01 hours.
