Nanedi Valles (Mars)

Word for "planet" in Sesotho, national language of Lesotho, Africa.

Nanedi Valles is located. Its shape is similar to that of Nirgal Vallis, being very sinuous and having only a few short branches. Unusually for Martian valleys, the individual channel structures within the wider valley floors can occasionally be seen in this system. (wikipedia entry)

A vallis is a valley. On Mars large valles are named after words for Mars/star in various languages. Small valles are named after classical or modern names of rivers.
