Tython system The Tython system , also known as the Tythan system , was a star system located within the Deep Core . Centered around the star Tythos , the system contained eleven planets , including the planet Tython , which was the homeworld of the Je ' daii Order thousands of years before the founding of the Galactic Republic . The system was settled for a time by the Kwa in the millennia before the Tho Yor Arrival in 36 , 453 BBY , when the eight great pyramid ships known as the Tho Yor brought Force - sensitive pilgrims of many different species to Tython to study the Force . Over a thousand years later , the non - Force - sensitive Tythan s spread out over the Settled Worlds , as the system ' s planets became known . History . Around 29 , 000 BBY , the Tythans conducted a series of exploratory missions to Sunspot , hoping to discover signs of habitation that would prove that the planet did not originate in the Tython system but was in fact a rogue planet caught in Tythos ' s gravity . However , the missions were ultimately unsuccessful . Orbital bodies . Sunspot . Sunspot was a small planet that was the closest to Tythos in the system , though it moved along its orbit in a direction opposite that of the other planets in the system , and it was believed by Tythan scientists that Sunspot was actually a " rogue " planetoid that had been caught in Tytho ' s gravitational pull . Sunspot ' s orbit took it as close as forty - eight million kilometers from Tythos at times , and much of the planet ' s surface was in constant turmoil as it was racked by gravitational forces that caused violent seismic and volcanic activity . Petonium and marionium , elements that were used to power ships ' drives , were among the elements found on Sunspot . Most of the planet ' s settlers lived at the poles in scattered mining communities , and 10 % of those who came to Sunspot seeking their fortune died there — most miners only lasted one or two seasons before they left the world . Sunspot ' s surface was covered by volcano ranges and magma lakes and rivers , and the clouds of noxious gas occasionally led the planet to have a pinkish hue from space . Sunspot and Malterra ' s orbits caused the planets to pass very close to each other at a certain point , resulting in violent storms on both planets as they passed within half a million kilometers of each other . Sunspot ' s surface was extremely hot , but the Tythans developed environment suits that allowed them to conduct mining operations on the planet ' s surface . Malterra . Malterra was the second planet closest to Tythos in the system . When the small planet passed Sunspot , the planet closest to Tythos , in its orbit , violent storms were often experienced . While it was known to have an extremely hot climate , many non – Force - sensitive settlers still colonized Malterra , more than thirty - six thousand years before the Battle of Yavin . Mawr . Mawr was the tenth planet in the Tython system , a large gas giant with seven moons that was one of the two largest in the system along with Obri . An orb of black and reddish orange gas , Mawr was known as one of " the Giants " along with Obri . Several gas - mining facilities had been established in Mawr ' s atmosphere by the year 25 , 793 BBY , and Mawr ' s moons were colonized by the Tythans during the second migration . Furies Gate . Furies Gate was the outermost planet in the Tython system , and it was a barren world less than a third of the size of Tython that was unsettled apart from Fury Station , a space station in orbit of the planet . Fury Station was a scientific outpost , and also served as a launch point for several of the sleeper ship s that the Tythans sent out into the galaxy , which eventually settled Empress Teta , Coruscant , and Corellia . Furies Gate featured a barren red surface and lacked any moons , and its distance from Tythos led it to be a cold world .
