(14612) Irtish Main-belt Asteroid
Discovered on 18 September 1998 by E. W. Elst at La Silla.
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.Naming citation (20060413/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
