14612 Irtish           Discovered 1998 Sept. 18 by E. W. Elst at the European Southern Observatory.
The Irtish river has its source on the icy slopes of the Mongolian Altai Montains in China. About 600 km of its 4250-km length pass through Chinese territory and 1200 km traverse the arid steppes of Kazakhstan. Entering Russia near Omsk, it passes the city of Tobolsk and eventually flows into the Ob.
