19776 Balears           Discovered 2000 Aug. 4 by J. Nomen at Ametlla de Mar Observatory.
The people of the western Mediterranean group of islands Mallorca, Menorca, Ibiza and Formentera, known as the Balears (or Balearic Islands), have a distinct culture and history. The name of the islands was given by Greek navigators after suffering the accurate sling shots (ballein) thrown at them by the islanders.
