(4715) 1989 TS1 is a carbonaceous Jupiter trojan from the Trojan camp, approximately 63 kilometers in diameter. It was discovered on 9 October 1989, by Japanese astronomer Yoshiaki Oshima at the Gekko Observatory in Shizuoka Prefecture, Japan.[2]
Photometric observations of this asteroid during 1991 were used to build a light curve showing a rotation period of 8.8129 ± 0.0025 hours with a brightness variation of 0.46 ± 0.01 magnitude.[9]
