Mu Draconis, 21 Draconis

Image of Arrakis

The view from a hypothetical planet in the Arrakis system. Bright in the sky are the twin stars that make up the core of the system. The third and more distant component, Arrakis C, shines like a 'morning star'.

The name Arrakis comes from Arabic, and means 'The Dancer'. This is indeed an appropriate name for a three-star system, where the two major components are almost identical stars rotating around their common centre of gravity. A third, fainter, star pursues a more distant orbit around these two.
