(6090) 1989 DJ is a Jupiter Trojan minor planet. A part of the Greek camp, it lies at the L4 Lagrangian point. It was discovered by Henri Debehogne at the La Silla Observatory in Chile on February 27, 1989.
Photometric observations of this asteroid during 2009 were used to build a light curve showing a rotation period of 18.476 ± 0.007 hours with a brightness variation of 0.16 ± 0.01 magnitude.
