Please note: this information pertains to a Near-Earth Object (NEO). During close approaches, our current computational model is not able to provide an accurate position, due to the high speeds of these objects. We plan to refine our algorithms to improve accuracy in the future. JPL Horizons can compute precise positions in these situations.
