5751 Zao,
Sendai Astronomical Observatory
on 5 January 1992
Physical properties
Zao has been observed by several groups to determine its rotational period. Its
albedo of 0.36 and re-classify the asteroid from X-type to E-type.[6] Using the asteroid's albedo and the Near Earth Asteroid Thermal Model (NEATM) the asteroid's diameter was estimated to be 2.3 km.[6] Further study of the asteroid by the Ondrejov Asteroid Photometry Project concludes that a rotational period of 76 hours is consistent with earlier measurements.[3][7]
