29402 Obelix           Discovered 1996 Oct. 14 by M. Tichy and Z. Moravec at Klet.
Obelix is Asterix's devoted friend in the cartoon series Les aventures d´Asterix by Uderzo and Goscinny. A menhir delivery-man by trade, he is always ready to drop everything and go off on a new adventure---so long as there's wild boar to eat, and plenty of fighting.
