5130 Ilioneus (1989 SC7) is a Jupiter Trojan discovered on September 30, 1989, 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 14.768 ± 0.014 hours with a brightness variation of 0.16 ± 0.01 magnitude.[2]
