It was named after the Greek hero Neoptolemus, the son of Achilles. It was discovered by the Purple Mountain Observatory in Nanjing, China on November 26, 1975. Photometric observations of this asteroid during 2002 were used to build a light curve showing a rotation period of 8.180 ± 0.008 hours with a brightness variation of 0.32 ± 0.01 magnitude.〔 ==References==
