The application includes 3D models of 30 objects in the Solar System, 3200 nearby stars, a large database, containing textual descriptions of all objects in a scene, interactive map of constellations and tools for search and navigation. The methods, needed for visualization of different scale astronomical objects in virtual environment, are described.
