Asteroid 16755, Cayley, was discovered on September 9, 1996 by Paul G. Comba at Prescott, Arizona. It has a period of 4 years, 63 days.
It was named for British mathematician Arthur Cayley (1821-1895), a onetime attorney turned Cambridge math professor who published extensively on algebra and geometry and co-founded the theory of algebraic invariants.
