6827 Wombat           Discovered 1990 Sept. 27 by T. Urata at the Nihondaira Observatory.
Three species of this marsupial inhabit Australia and Tasmania. The common wombat is the most widespread. The southern hairy-nosed wombat is restricted to arid regions. The northern hairy-nosed wombat is apparently on the brink of extinction.
