(23258) Tsuihark is a main inner belt asteroid discovered on December 29, 2000 by the Canadian astronomer of Hong Kong origin William Kwong Yu Yeung at the Desert Beaver Observatory near Eloy , Arizona ( IAU code 919).
Mean solar distance ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid are similar to the orbital data of the members of the Flora family, a large group of asteroids named after (8) Flora . Asteroids of this family move in a 4: 9 orbital resonance with the planet Mars around the sun . The group is also called the Ariadne family, after the asteroid (43) Ariadne .
(23258) Tsuihark was named on March 28, 2002 after the film director and producer Tsui Hark .
