Stellarium is a software project that allows the user to use your PC as a virtual planetarium. E ‘can calculate the position of the sun, moon, planets and stars, and play in the sky as they would appear to an observer at a given place and at any given time.
It can also draw the constellations and simulate astronomical phenomena such as meteor showers, eclipses of the Sun and Moon. Stellarium can be used as an educational tool for teaching the starry sky at night, as an aid for observational astronomy who wish to schedule a full observing, or simply for pleasure and curiosity.
