3554 Amun is an M-type Aten asteroid (meaning it crosses Earth's orbit) and a Venus-crosser. It was discovered on 4 March 1986 by Carolyn and Eugene Shoemaker at Mount Palomar Observatory. Its estimated diameter is 2.48 kilometers, making it one of the smallest known M-type asteroids. Amun was the fifth Aten asteroid to be numbered.
(6178) 1986 DA is another M-type near-Earth asteroid with lower inclination that is actually metallic.
Amun passes closest to Venus, and in 1964, 2034, and 2103 comes within 10 Gm of it.
