9172 Abhramu           Discovered 1989 July 29 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
Abhramu, the "cloud-knitter", was the original female elephant who was a supernatural winged being who could change her shape at will, like the clouds that resemble her children. According to Indian legend, Abhramu's tribe lost its wings and magic by mischance.
