Planetary Observational Data
The creation of modern ephemerides involves the fitting to a wide variety of astronomical measurements (observations). This page presents the sets of observations that are currently being used in the creation and improvement of modern planetary and lunar ephemerides.
These data are currently maintained by Ryan Park; JPL/Caltech (email@example.com).
