5638 Deikoon (1988 TA3) is a Jupiter Trojan discovered on October 10, 1988 by Shoemaker, C. S. at Palomar.

Photometric observations of this asteroid during 1994 were used to build a light curve showing a rotation period of 9.137 ± 0.003 hours with a brightness variation of 0.07 ± 0.01 magnitude.[2]
