See Sun rise and Sun set in Real time on your Computer

Stellarium is a free open source planetarium for your computer. The software renders realistic skies in real time just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors.

Computer with reasonable configuration should be able to run Stellarium. It supports Linux, Windows and Mac. Installation is just like regular software. After installation run the software.

1. Set your location first (default location is Paris, France). You can click on your location on the map in the configuration window (Select ‘configuration window’ menu from the screen below left side), or enter coordinates manually and save the changes by clicking "set as default". From now on, the sky will look exactly as it looks where you live when you run Stellarium. If you take Stellarium along on a trip with a laptop, you will need to adjust your location of course.

2. Use the mouse or arrow keys to look around.

3. Use the page up and page down keys to zoom in and out.

4. Use the left mouse button to select an object, the right button to deselect the object and middle mouse button or spacebar to center on the selected object.
