What does ALGOL mean in Arabic?

Algol is one of the best known variable stars in the sky and a prototype for a class of eclipsing variable stars known as Algol variables . It is a triple star system composed of Beta Persei Aa1, a B-class main sequence star, Beta Persei Aa2, an orange subgiant, and Beta Persei Ab, a dimmer A-class star.

Algol is at minimum light for about 20 minutes — as the large, dim star passes across the smaller, brighter one — then it gradually returns to normal. Algol brightens and fades almost like clockwork, but nonetheless, is still subject to small, complex changes which are of considerable interest to astronomers.

ALGOL, computer programming language designed by an international committee of the Association of Computing Machinery (ACM), led by Alan J. Perlis of Carnegie Mellon University, during 1958–60 for publishing algorithms, as well as for doing computations .

The name Algol derives from Arabic رأس الغول raʾs al-ghūl : head (raʾs) of the ogre (al-ghūl) (see “ghoul”). The English name Demon Star was taken from the Arabic name.

from the Earth to Sun in distance. FACT: All Stars and Planets orbit round a central point, the planets orbit the Sun and the Stars orbit the Galactic Centre. The Star Algol is located approximately 24,214,37 light years (7,424.00 parsecs) from the Galactic Center, the center of the galaxy we call the Milky Way .
