Excerpt: 5751 Zao also designated 1992 AC is an Amor asteroid discovered on January 5, 1992 by M.

Koishikawa at the Ayashi Station of the Sendai Astronomical Observatory. 5751 Zao has been observed by several groups to determine its rotational period. Its light curve was observed by Pravec, et al. between 1992 and 1995 with the intention of determining its rotational period. From its nearly constant brightness it was determined that the asteroid is roughly spherical and has a rotational period of 21.7 hr.

Another group led by Wisniewski conducted an approximately 5 hour observation and were unable to conclude a rotational period. 5751 Zao was again observed in 2001 by Delbo, et al. using the Keck telescope. They were able to determine the asteroids albedo of 0.36 and re-classify the asteroid from X-type to E-type. Using the asteroids albedo and the Near Earth Asteroid Thermal Model (NEATM) the asteroids diameter was estimated to be 2.3 km. Further study of the asteroid by the Ondrejov Asteroid Photometry Project concludes that a rotational period of 76 hours is consistent with earlier measurements.
