Stellarium is a planetarium tool for beginning astronomers. It allows users to observe the night sky in real-time. The tool will show you the sky above your location. An astronomer can zoom in to get a better image of the stars and constellations. Moreover, all the space bodies will be marked - that makes Stellarium an amazing teaching tool.

A user can choose objects for display thanks to the flexible system of filters. Stellarium allows you to observe stars, planets, galaxies, star clusters, nebulas, and other deep space objects. In order to conduct daytime observations, an astronomer can fast-forward the programme to see the night sky anytime.

Why Use Stellarium?

The interface of Stellarium is lightweight and easy to use. The program is designed to not distract a user from sky observation - that’s why all the controls are placed in a compact panel in the bottom of the screen. There’s a built-in zoom-in designed to improve the precision of observation, though the quality of zoomed images needs further improvement.

In case you’re a beginning astronomy enthusiast, there’s a variety of helpful tools to familiarize yourself with the sky. For instance, a user can enable the constellation contour feature - it’ll help you identify and memorize constellations and improve the skill of identifying them outdoors.

Stellarium also has a search feature that’s handy when navigating the sky. You can search the names of stars, planets, and other space bodies. The program offers a built-in telescope feature as well to make the observations as close to the physical ones as possible. You can navigate through lenses or activate a binocular mode.

There’s a possibility to upload and analyze 360-degree pictures. In order to improve your knowledge about space bodies, use a built-in catalog. Apart from providing the information on thousands of solar system objects, you’ll be notified, in case a new comet is discovered.

Stellarium Main Features:

  • Built-in database for 600 00 stars;
  • Real-time night sky observation;
  • Zoom-in feature;
  • A wide variety of supported lenses and binoculars;
  • Learning tools to help identify a constellation or other solar system objects;
  • Virtual on-site observation;
  • Easy-to-use interface.


Stellarium is a tool for a virtual astronomic observation that can come in handy both for professional scientists and beginners. It improves the observation experience as well as gives access to a knowledge database with the data on over 600,000 stars.
