Asteroid 9000 Hal is a main belt asteroid with an estimated diameter of 10 km. It was discovered on May 3, 1981 by Bowell, E. at Anderson Mesa. The semi-major axis is 2.22 AU, the eccentricity is 0.209 and the inclination is 6.26 degrees.
Observations of this asteroid were made on seven nights between July and September, 2008. Unfortunately the scatter in the data was almost as great as any variation and a reliable period could not be determined.
