The ICRF is the best realization of an inertial frame constructed to date, and thus represents an improvement upon the theory behind the J2000 frame. While the ICRF and J2000 frames themselves are very close, they are not identical; moreover, the J2000 frame rotates (very slowly) over time with respect to the ICRF frame.

Spice Body List Provides a listing of the SPICE segments from the SPICE ephemeris files (i.e., *.bsp files) that have been loaded and sorted by body id.

Each segment contains data (indicated by the segment type) to generate ephemeris for one body (indicated by the body id). The data uses a reference origin (indicated by the center id) and a reference frame (indicated by the frame id). The span of the ephemeris data is reported by the Start Time and Stop Time.

SPICE uses a priority scheme to resolve conflicts when more than one segment contains ephemeris for the same body id: see the description for Status.
