Named for a son of Odin and Frigga {see planets  (3989) and  (77)} in Scandinavian mythology. He entered the land of the dead, guarded by Hel {see planet  (949)}, in an attempt to rescue his brother Balder {see planet  (4059)}. Hel agreed on condition that everyone and everything in the world, even the plants, stones, and metals, should mourn for Balder. All did, except for a single giant witch in a cave, Thokk.
