I have edited the description. It is not useful to record the positions of objects within the solar system (Moon, Saturn, etc.) in WikiData because they change too rapidly. The kind of objects which would have position information stored in WikiData would be stars, quasars, pulsars, galaxies, and the like. The kind of objects and the kind of data available for them can be explored at the US Naval Observatory's NOMAD catalog <http://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/nomad>. Modern star catalogs use the International Celestial Reference System. Except for the most accurate data, this is equivalent to a system centered on either the barycenter of the solar system or the center of the Sun, using the equator and equinox of J2000.0 (a date close to the beginning of the year 2000.
