The disks of the sun, moon, and planets are not drawn to scale. Their brightnesses are given as magnitudes to the right of their names. A more negative magnitude means a brighter planet. The magnitudes given for Saturn do not include the brightness of the rings, so Saturn will usually be brighter than indicated. This program is only designed to have a limited degree of accuracy, sufficient for most naked- eye astronomy applications.

You are welcome either to link to my Planet Finder page or to have the applet appear in your own page. A possible advantage of the latter is that in your html code you can set an appropriate language, latitude, and longitude for the people who visit your page. Note that, due to a bug, the latitude and longitude as set in the html code must be integers. If you would like to do this, please e-mail me for instructions. It is quite easy to do, and requires no programming expertise.
