1282 Utopia is a main-belt asteroid discovered on August 17, 1933, by South African astronomer Cyril V. Jackson at Johannesburg (UO). It was assigned the preliminary designation 1933 QM1.
Photometric observations at the Palmer Divide Observatory in Colorado Springs, Colorado, from 1999–2006 were used to build a light curve for this object. The asteroid displayed a rotation period of 13.61 ± 0.01 hours and a brightness variation of 0.28 ± 0.01 in magnitude.[2]
