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.

| 11517 Esteracuna | Discovered 1991 Mar. 12 by H. Debehogne at the European Southern Observatory. |
| Maria Ester Acuna Castillo (b. 1951) was a caretaker at the Manuel Foster Observatory for several decades. She assisted astronomers during observations with the historical single-prism spectrograph mounted on a replica of the Lick Observatory telescope on Cerro San Cristobal in the heart of Santiago de Chile. |
