(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.

## Mars-Crossing

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.[1]

## Moon

1992 AX has one natural satellite, S/1997 (5407) 1. However, the true presence of a moon is still considered inconclusive.[2] 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.[2] From the surface of 1992 AX, S/1997 (5407) 1 would have an angular diameter of roughly 14.3°.[a] For comparison, the Sun appears to be 0.5° from Earth.
