numbered
.
rotation period of 2.53029±0.00002 hours.[3] It has been classified as an M-type asteroid in the Tholen taxonomy, X-type in the Bus taxonomy, and C-, X-, and D-type in the Bus-DeMeo taxonomy. The featureless optical spectrum has a similar slope to the Tagish Lake meteorite, although 3554 Amun is not considered the source.[4] The infrared spectrum of 3554 Amun was found to match a D-type asteroid taxonomy.[5] The estimated diameter is 3.341 kilometers,[1] making it one of the smallest known asteroids to have an M-type classification.[citation needed

Amun was once considered metallic, based on an M-type optical spectrum. In Mining the Sky, planetary scientist John S. Lewis calculated the purported value of a metallic 3554 Amun at $20 trillion.[6] (6178) 1986 DA is another M-type near-Earth asteroid with lower inclination that is actually metallic.
Amun passes close to Venus, and in 1964, 2034, and 2103 comes within 10 Gm of it.[1]
