Asteroid 3554, Amun, an Aten asteroid, was discovered on March 4, 1986 by Carolyn and Eugene Shoemaker at Mount Palomar Observatory near Pauma Valley, California. It has a period of 350 days and is about a mile and a half in diameter.
It was named for Amun, the supreme god of the Egyptian pantheon.
Astrologically, asteroid Amun seems to mean to attain, to overcome, to conquer, to get past or around.
The glyph for Amun is mine and is based on the ancient Egyptian symbol for the god (two parallel plumes).
