) contains details of the locations of
selected objects in the Solar System.
The trajectories table contains the locations of all major planetary objects
and of spacecraft that have travelled on a complex trajectory.

for the inner planets the cadence is four values per day.
Other tables contain the locations of spacecraft that are in orbit around certain planets.
These locations are generally at a much higher cadence.
The ILS also contains a table of the dates of Key Events in the life of several
spacecraft including launch, planetary flybys and insertion into orbit around the target
