Stellarium is an open source software for your computer which is free. It shows a realistic 3D sky, as can be seen with the naked eye, with binoculars or a telescope. It uses in the projectors of the planetarium.

Stellarium makes 3D Realistic Sky in real time with OpenGL. It shows stars, constellations, planets, nebulas and other things like earth, landscape, atmosphere, etc.

Probably, few people have heard of Stellarium, although it is very similar to one of the most popular programs in today's world, Google Earth. While Google's software allows it to focus on the Earth from a cosmic point of view, Stellarium changes its point of view and places it anywhere on the surface of the earth, looking up and down in the space.

An exciting feature of Stellarium is that over time the virtual star system will evolve, and the sunset and several constellations will become more visible in the night sky. It has many visual effects that can be activated or deactivated.

While Google Earth provides you with detailed images of the surface of our planet, Stellarium can obtain a much lower resolution of the planets of the solar system, not to mention the fact that the stars are limited to white points that shoot at the sky. With more than 120,000 stars represented with precision in this virtual planetarium, it is evident that much has been done to create this planet.

The ​​Stellarium is a good idea in theory, but when it comes to most people, you will only see it as an intelligent and interactive protector. In other words, if you have proximity to astronomy, want to learn constellations or merely enjoy beautiful sunsets, then Stellarium exists for you.

Stellarium brings astronomers of all levels of interest to an astronomical level. It is not as severe as the competition, but it is also a much faster program. At startup or work, it does not take your RAM to a black hole. It works only in full-screen mode, which makes other programs available inaccessible, except for the ALT tab button.

The standard catalogue contains 600,000 stars, with update packages that can increase the number to 210 million stars. Constellations from 10 different cultures are included, as well as illustrations and constellations that will help you imagine what the ancients saw. There is also a full catalogue of Messier Nebulae. The origins of the sunrise, the twilight and the atmosphere were good, but not very good in our monitor. They can be seen better in the planetary dome, so it is useful that Stellarium also has the shape of a fisheye for curved surfaces. In addition to the equatorial and azimuthal grid, users also have shooting stars, Eclipse models and landscapes with the ability to draw. Stellarium contains stellar views of the moon.
