Interactive Sky Chart
Create a custom naked-eye map of the whole sky for any place on Earth, at any time of day or night, on any date from 1600 to 2400. Our Interactive Sky Chart works in most Java-enabled Web browsers.
Note: This schematic chart tells where stars and planets are located with respect to your horizons and zenith. For a bigger, more realistic chart for easiest use outdoors, see Sky & Telescope or our annual SkyWatch.
If the Sky Chart fails to work properly, please reinstall your Java plug-in available free from java.com. You may also need to activate the Java plug-in manually. For best results on a PC, use Internet Explorer 6 or higher or Netscape 7; on a Mac, use OS X 10.3 with Safari.
For more information, or if you have trouble getting the Sky Chart to open or print, please review our system requirements.

Note that if you've installed a "pop-up stopper" to block advertisements that automatically open in new browser windows, you'll probably have to turn it off, as our Interactive Sky Chart needs to open in a new browser window.
