[3] The first precovery was obtained at Siding Spring Observatory in July 1977, extending the asteroid's observation arc by 22 years prior to its discovery.
[1] Campai has been characterized as a common, stony S-type asteroid,[5] in line with the overall spectral type for members of the Witt family.
[8]: 23 In October 2010, a rotational lightcurve of Campai was obtained from photometric observations made at the Palomar Transient Factory in California.
[6] While the result is based on less than full coverage, and may be refined by future observations, Campai is one of the slowest rotating asteroids known to exist.
[5] This minor planet was named for Italian amateur astronomer Paolo Campai (born 1957) from Florence, who is specialized in teaching and astrophotography.
