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, for any year between 1600 to 2400. Our Interactive Sky Chart requires Java to work.
The schematic chart tells you where stars and planets are located with respect to your horizons and zenith. The window to the left shows your view along the horizon, and to the right you'll see a full-sky chart. You can even print the chart to use it outdoors. Have fun with it! For example, see Fun with S&T's Interactive Sky Chart to find out if the constellations really are upside down on the other side of the equator.
Log in at the top right corner to use the Interactive Sky Chart or, if you're not already registered with our website, register now — it's simple and free.
