Asteroid 13387, Irus, a Jupiter Trojan, was discovered on December 22, 1998 at the Astronomical Observatory of Farra d'Isonzo in Farra dŽIsonzo, Gorizia, Italy. Apparently the observatory gets the discovery credit. Irus has a period of 11 years, 341 days.
It was named for a character from The Odyssey: the beggar Irus (so nicknamed by Penelope's suitors because he ran errands for them, like the goddess Iris did with the Olympian gods) defied and was defeated by Odysseus on his return home.
Astrologically, Irus seems to indicate sending messages, being used as a messenger .
The glyph for Irus is mine.
