For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

33377 Večerníček           Discovered 1999 Feb. 12 by P. Pravec at Ondřejov.
Večerníček is an animated figure accompanied by music. It invites children to the Czech Television to see a bedtime story every evening. Ingeniously painted by R. Pilař, voiced by M. Citavý, and with the tune composed by L. Simon, it has become a real phenomenon loved by most Czech children since 1965.
