Planet Applet: Mercury, Venus, Mars, Jupiter, Saturn, and the Moon
Please be patient, 590 kB of Java code to be loaded ...

The bright planets - Mercury, Venus, Mars, Jupiter, Saturn - as well as the Sun and the Moon (The seven wanderers known to the ancients), are the subjects of this applet. It provides different views: a diagram showing the rise and set times over the year, a view at the local horizon (rectangular, spherical, and polar), a view of the ecliptic plane, a sky map, and an earth map.

In case the applet is not running, click here

You may use the keys y, m, w, d, h, n to increase the yaer, month, week,date, hour, or minute,
or Shift key and y, m, w, d, h, n to decrease the year, month, week,date, hour, or minute.
Use c or shift key and c to increase/decrease the century.

Detailed applet info and help

Check your time zone offset and the local time.
(The value selected is derived from the longitude)

Enter latitude in decimal degrees and press return key,
enter longitude in decimal degrees and press return key.

The View menu provides 8 views:

1. a Diagram showing the rise and set times over the year, 3 different representations.
2. a view at local the Horizon (rectangular coordinates),
3. a view at local the Horizon (spherical projection),
4. a view at local the Horizon (polar coordinates),
5. a view of the Ecliptic plane,
6. a view of the orbit of the Moon around the Earth,
7. a Sky Map,
8. an Earth Map.

The items of the Details menu, working in toggle mode, show and hide additional details.
"Horizon Image" changes the background image of the Horizon View.
