8709 Kadlu           Discovered 1994 May 14 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
The Eskimo thunder-goddess was originally a little girl who played so noisily that her parents told her and her sisters to go outside to play. They did, and they invented a game in which Kadlu jumped on hollow ice, causing a thunderous sound. Transported to the sky, the goddess lived in a whale-bone house far in the west. Some legends say that Kadlu made thunder by rubbing dry sealskins together, or by singing.
