378214 Sauron           Discovered 2007 Jan. 14 by E. Schwab and R. Kling at Taunus.
Sauron is a fictional character in J. R. R. Tolkien's fantasy novel The Lord of the Rings. He created the One Ring to rule the rings of power. Due to Sauron's war-like nature, a Mars-crossing minor planet was chosen to receive his name.
