Stellarium es un programa gratuito de código abierto. Es capaz de mostrar un cielo realista en 3D, tal como se aprecia a simple vista, con binoculares o telescopio.
Actualmente se ha implementado en domos planetarios. Sólo especifica las coordenadas y listo.

más de 120,000 estrellas del catálogo Hipparcos con información adicional
asterismos e ilustraciones de las constelaciones
imágenes de nébulas
Vía Láctea realista
atmósfera realista, salida y puesta del sol
los planetas y sus satélites

Lista de Cambios:
- Larger star catalog including stars from Hiparcos, Tycho2 and NOMAD
- Can select multiple constellations at one time
- Local script directory is reread when enter TUI
- Inuit constellation art by Johan Meuris
- More sky cultures
- Large code reorganization into a modular structure based on StelModule, StelApp singleton and its “manager” classes providing services to the modules
- Projection code cleaned and splitted into Mapping classes
- Movement control code encapsulated into the MovementMgr module
- Code cleaning and commenting
- Sidereal day/week keystrokes (ALT -, ALT =, ALT [, ALT ])
- Data files reorganized
- Added back Hawaiian translations (invented locale “hw”)
- Orthographic projection, Lamberts Equal Area projection, Cylinder projection
- Interpolate the elliptic coordinates (or the spherical coordinates in case of the moon)
- Do not place the Earth at the EMB but at its proper position
- New orbit type comet_orbit for proper calculation of elliptic, parabolic, hyperbolic orbits
- Added loading of jpeg textures and re-coded most of the texture manager
- Allow loading of plug-ins (unstable until version 1.0)
- Selection of object is managed per module, and by the StelObjectManager
- Recoded Grid display to allow for adaptative scale wrt zoom and labeling
- The main window managed by QT4.2 instead of SDL
- Window resizing
- Smooth go to selected solar system body by pressing control-g
- Location map updates on changing observer to new solar system body
- Titlebar updates after moving to new planet
- Landscapes may now have location, can update observer by selecting landscape
- More nebula textures and better placement of most existing textures
- Build is now managed by cmake instead of autoconf/automake
