According to the international asteroid naming rules, asteroid naming is serious, unique and permanently immutable, and is an international and permanent noble honor.

According to Wu Xuefeng, deputy director of the Purple Mountain Observatory of the Chinese Academy of Sciences, on February 6, 2008, when observing the constellation Leo, the Purple Mountain Observatory discovered a new asteroid, which was 184 million kilometers away from the earth. The Lovell Observatory, Catalina Observatory, Mount Lemont Observatory, Lincoln Laboratory and other institutions in the United States have confirmed the existence of this asteroid and further calculated the precise orbit after many observations. The International Minor Planet Center gave the asteroid 420612 a permanent number in January 2015 and confirmed that the Purple Mountain Observatory had the right to name the object.

Nanyou Star has an orbital eccentricity of 0.098, an orbital inclination of 11.29 degrees, an orbital semi-length of 2.344 astronomical units, an average distance of 349 million kilometers from the sun, 3.59 years to orbit the sun, and orbit the sun at high speed at a speed of 19.4 kilometers per second. Its maximum distance from the Earth is 535 million kilometers and its closest distance is 167 million kilometers.
