(3556) Lixiaohua is an asteroid of the main belt , which on 30 October 1964 at the Purple Mountain Observatory in Nanjing was discovered.
The asteroid was named after Li Xiaohua, a Beijing entrepreneur who founded many elementary and middle schools in remote Chinese locations.
The asteroid belongs to the Gantrisch family . This group of asteroids was previously called the Lixiaohua family until (3330) Gantrisch was assigned to the group, which, with its 35 km diameter, replaced the 20 km large (3556) Lixiaohua as the largest member of this family. Sometimes the old family name is still used.
The asteroids of this family have relatively chaotic orbital parameters seen over a long period of time, as several large asteroids in their vicinity such as (1) Ceres , (2) Pallas , (4) Vesta , (10) Hygiea , (52) Europa , (511) Davida and (704) Interamnia influence their orbits. It is believed that the members of this family formerly formed an original body about 220 km in size, which disintegrated about 155 million years ago in a cosmic catastrophe, as simulations of the asteroid orbits suggest.
