The applet which you can see in the separate window shows
the orbits of the planets and the moon. The positions of the
planets and moon are shown for the set date, which can be any
number of days before or after 1st January 2000, the number of
days being set with buttons. The scale can also be set.
The phase of the moon is separately illustrated.
Unfortunately you need a fast computer to show this orrery
efficiently. If you hold down a plus or minus button, the number
of days should change twice per second.
