astronomers use flux to denote the apparent brightness of a celestial body. the apparent brightness is defined as the amount of light received from a star above the earth atmosphere passing through a unit area each second. therefore, the apparent brightness is simply the flux we receive from a star.

& kstars; displays thousands of celestial objects: stars, planets, comets, asteroids, clusters, nebulae and galaxies. you can interact with displayed objects to perform actions on them or obtain more information about them. clicking on an object will identify it in the status bar, and simply hovering the mouse cursor on an object will label it temporarily in the map. double-clicking will recenter the display on the object and begin tracking it (so that it will remain centered as time passes). right clicking an object opens the object's popup menu, which provides more options.
