(5407) 1992 AX is a Mars-crossing minor planet. It was discovered by Seiji Ueda and Hiroshi Kaneda in Kushiro, Hokkaidō, on January 4, 1992.
1992 AX makes occasional close approaches to Mars. Its next close approach, on January 22, 2027, will bring it 11,260,000 km (0.0753 AU) from Mars.
1992 AX has one natural satellite, S/1997 (5407) 1. However, the true presence of a moon is still considered inconclusive. If it exists, the moon completes one orbit around 1992 AX every 13.5196 hours at a distance of 6.8 km. S/1997 (5407) 1 is 1.2 km wide. From the surface of 1992 AX, S/1997 (5407) 1 would have an angular diameter of roughly 14.3°. For comparison, the Sun appears to be 0.5° from Earth.
