[2] Nikko orbits the Sun in the inner main-belt at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,222 days).
[1] Between 2004 and 2011, several rotational lightcurves of Nikko were obtained from photometric observations taken by astronomers Laurent Bernasconi,[8] Hiromi and Hiroko Hamanowa,[8] John Menke,[12] Robert Stephens,[9] as well as at the Palomar Transient Factory in California.
[6] Lightcurve analysis gave a rotation period between 3.781 and 3.792 hours with a brightness variation between 0.26 and 0.50 magnitude (U=3/3/3/3-/2/2).
[3] This minor planet was named for the Japanese city of Nikkō, located in the Tochigi Prefecture of central Japan.
The tourist resort is known for its Shinto shrine and a UNESCO World Heritage Site Nikkō Tōshō-gū.
