Open-source planetarium

Stellarium is a free and open-sourceplanetarium, 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 being developed by Noctua Software.

These have a limited functionality, lacking some features of the desktop version.

All versions use OpenGL to render a realistic projection of the night sky in real time.^{[citation needed]}

Stellarium was featured on SourceForge in May as Project of the Month.^[3]

After Fabien Chereau took control of the Stellarium he stopped supporting old version of Stellarium software costing 20 dollars in App Store and created different instance of Stellarium there selling this software again so old loyal users have to buy it again.

However as of users can install it free.

History

In , Stellarium won a gold award in the Education category of the Les Trophées du Librefree software competition.^[4]

A modified version of Stellarium has been used by the MeerKAT project as a virtual sky display showing where the antennae of the radio telescope are pointed.^[5]

In December , Stellarium was added as one of the "featured applications" in the Ubuntu Software Center.^[6]

Planetarium dome projection

The fisheye and spherical mirror distortion features allow Stellarium to be projected onto domes.

Spherical mirror distortion is used in projection systems that use a digital video projector and a first surface convex spherical mirror to project images onto a dome. Such systems are generally cheaper than traditional planetarium projectors and fish-eye lens projectors and for that reason are used in budget and home planetarium setups where projection quality is less important.^{[citation needed]}

Various companies which build and sell digital planetarium systems use Stellarium, such as e-Planetarium.^{[7][non-primary source needed]}

Digitalis Education Solutions, which helped develop Stellarium, created a fork called Nightshade which was specifically tailored to planetarium use.^{[8][9][non-primary source needed]}

Images: Ukuran Bulan yang terlihat dari Bumi kira-kira sama dengan ukuran Matahari. Akan tetapi, ukuran Matahari jauh lebih besar daripada ukuran Bulan; jarak antara Matahari dan Bulan yang sangat jauh menyebabkan ukuran kedua benda langit ini tampak sama dari Bumi.

It is no longer supported or maintained; the last version was , dated January 15, ^{[10][non-primary source needed]}
