It was discovered on 7 November 1978, by American astronomers Eleanor Helin and Schelte Bus at the Palomar Observatory in California.
[4] When applying the hierarchical clustering method to its proper orbital elements, the object is both a non-family asteroid of the main belt's background population (according to Nesvorný),[3] as well as a core member of the Themis family (according to Milani and Knežević).
[1] Janice is a presumed carbonaceous C-type asteroid which is the overall spectral type of members of the Themis family (602).
[4] In October 2010, a rotational lightcurve of Janice was obtained from photometric observations by Gordon Gartrelle at the University of North Dakota Observatory in Grand Forks (730).
