In the description
of the DE200 planetary ephemeris, it is pointed
out that, contrary to all the other
objects in the computation which use the

of our own moon is computed relative to the Earth - Moon barycentre, because then, the orbit integration will behave nicer numerically — which is good, as the Moon is an
object of special interest.
