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.

12697 Verhaeren           Discovered 1989 Sept. 26 by E. W. Elst at the European Southern Observatory.
The Belgian poet Émile Verhaeren (1855-1916), although writing exclusively in French, took much inspiration from "Flanders Fields", glorifying the greatness of its painters and enjoying the pleasures of its common people. Other important themes in his work are human progress, brotherhood of man and his love for his wife.
