Please be patient while the applet loads into your browser. Once it
loads, this applet will display a system of satellites orbiting
planets in our Solar System. Select a planet from the menus labelled
"High Resolution" and "Low Resolution", and the simulation will begin.
You may need to use your scrollbar to center the simulation on your
screen. You'll see a white window with several colored dots (trailing dots
as they move around). Clicking within this window will display the
coordinates in kilometers. In the window labelled "Selected Values",
the satellite name, elapsed time (in days) and positions (x and y
in thousands of kilometers) will be displayed if you click on one of
the moons. You may need to click "Stop" to aid your ability to select
the one you want. The initial positions are also displayed in a window
to the right, for reference. Please click on the icon (looks like an
x or a /) in the upper right corner of the simulation window before
selecting a second system -- only one should be running at a time.
