17452 Amurreka           Discovered 1990 Aug. 16 by E. W. Elst at the European Southern Observatory.
The Amour river in Russia flows across northern Asia from the mountains of northeastern China to the Sea of Okhotsk. With a length of 4444 km, the Amurreka drains diverse landscapes of desert, steppe, tundra and taiga. The river forms the border between the Russian Far East and northeastern China.
