The complicated system of Alula Australis contains two main stars both with red dwarfs orbiting close to them.  The main stars are two nearly identical g-class stars similar to Sol.  The stars orbit each other at an average distance of 21.2 AU, but there eccentric orbit brings them as close as 13 AU.  Orbiting the first star (Aa) is a red dwarf (Ab) at an average distance of 0.8 AU.  Looking at the skies of the primary planet Axia the two suns can be seen moving across the sky, also the second system (stars Ba, Bb) can be seen.  In the second system another red dwarf orbits close to star Ba in a four day orbit.  From planets in either system the other systems stars appear extremely bright (6000 times that of a full moon).  The system is one of the most unique in the galaxy, in few places can four different suns be seen rising and falling during the course of the day and night.


Alula Austalis A




Alula Australis Ab

A red dwarf star orbiting the star Aa at a distance of 0.8 AU.








The mountainous world of Axia orbits the yellow larger star Aa and the red dwarf Ab.  Both stars can be moving across the sky during the day.








Karida is a large moon orbiting Axia.  Numerous domed cities were built on the moon’s surface.  The domes protect the residents of the deadly vacuum caused by the lack of an atmosphere.







Malatus is an outer world orbiting stars Aa and Ab.  The planet is a cold world made up mostly of ice.  There is a thin atmosphere here.







Alula Australis B



Alula Australis Bb

A red dwarf orbiting star Ba in a four day torch orbit.  From the planets of the B system the two stars look extremely close.







Cordelia is an iron rich world orbiting the close binary system.  There are numerous small mining colonies scattered across the surface.







More distant and somewhat colder than Cordelia is the planet Nacrusia.  A thin atmosphere of carbon dioxide exists here.  The planet is similar to a blue version of Mars, the blue color caused by higher amounts of ice.
