It is assigned to the Lagrange point L 4 , that is (173086) Nireus is running 60 ° ahead of Jupiter in its orbit around the sun.
The asteroid was discovered by the Swiss physics teacher and amateur astronomer Michel Ory at the Jura Observatory ( IAU code 185) in Vicques in the canton of Jura on September 8, 2007. Ory was director of the observatory.
(173086) Nireus was named on March 21, 2008 at the suggestion of A. Martinez after Nireus , a king of the island of Syme , who had to take part in the Trojan War for the Greeks . Trojans running ahead are named after Greek heroes.
