Find out exactly when a certain planet that you're interested in will be visible in the sky and from which location on Earth you will be able to see it. The tool keeps a history with the position of the planets, displays the astronomical dawn as well as dusk and shows the cardinal direction of planets.

Asynx Planetarium is a software program built for users who are passionate about the Universe, its constellations, the movement of the planets, or the phases of the Moon. By using this software, users are able to find information about the stars and planets nearby.

The application has a pretty basic GUI and it comes with various panels and toolbars, and some customization options. Yet, the toolbar icons are crafted very poorly and some colors used for creating the main work area are simply badly chosen.

Asynx Planetarium allows viewing 88 constellations, more than 2500 stars, and all the planets of the Solar System. It has three distinct viewpoints, which can be modified with ease - horizontal sky, and geocentric and heliocentric views.

In order to find more details about a specific planet, star or constellation, users only need to click on that certain 'thing' and read the data card. It includes information regarding the name of that body, the temperature, the distance from the Sun, and the rotation period.

To sum it up, Asynx Planetarium is an innovative software solution for astronomy enthusiasts. It's free, easy to use and it offers important information about the Universe.
