Stellarium is a free and open-source planetarium, licensed under the terms of the GNU General Public License version 2 or any later version, available for Linux, Windows, and macOS. A port of Stellarium called Stellarium Mobile is available for Android , iOS , and Symbian as a paid version, being developed by Noctua Software.
A stellarium is a three-dimensional map of the stars, typically centered on Earth.They are common fixtures at planetariums, where they illustrate the local deep space.Older examples were normally built using small colored balls or lights on support rods (painted black to make them less obvious), but more recent examples use a variety of projection techniques instead.
Planetarium software is application software that allows a user to simulate the celestial sphere at any time of day, especially at night, on a computer.Such applications can be as rudimentary as displaying a star chart or sky map for a specific time and location, or as complex as rendering photorealistic views of the sky.

Neptune brightened about 10% between 1980 and 2000 mostly due to the changing of the seasons. [177] Neptune may continue to brighten as it approaches perihelion in 2042. The apparent magnitude currently ranges from 7.67 to 7.89 with a mean of 7.78 and a standard deviation of 0.06. [18] Prior to 1980, the planet was as faint as magnitude 8.0. [18]
SpaceEngine is an interactive 3D planetarium and astronomy software [2] initially developed by Russian astronomer and programmer Vladimir Romanyuk. [3] Development is now continued by Cosmographic Software, an American company founded by Romanyuk and the SpaceEngine Team in February 2022, based in Connecticut.
Celestial cartography, [1] uranography, [2] [3] astrography or star cartography [citation needed] is the aspect of astronomy and branch of cartography concerned with mapping stars, galaxies, and other astronomical objects on the celestial sphere. Measuring the position and light of charted objects requires a variety of instruments and techniques.
