Asteroid 2155 Wodan, was discovered on September 24, 1960 at Palomar Observatory near Pauma Valley, California as part of PLS (the Palomar-Leiden Trojan Survey). 130 photographic plates were taken at Palomar by Tom Gehrels and CJ Van Houten and Ingrid van Houten-Groeneveld examined them at Leiden University in Leiden, Zuid-Holland, Netherlands, detecting numerous asteroids, including Wodan.
Wodan has a period of 4 years, 303 days.
It was named for Wodan (Odin), the chief god of Teutonic mythology.
Henk Middleraad links asteroid Wodan with thunder, heavy action, powerful Pagan gods (objects of idolization or idolatry). It might also mean wooden.
