Jedi Temple Planetarium The Planetarium was a long chamber located at the base of the Tower of First Knowledge of the Jedi Temple on Coruscant . Situated next to the Tower ' s main entrance on the first level , it contained large bronzium replicas of several planetary bodies . History . Erected in the Tower of First Knowledge circa 1000 BBY , the Temple Planetarium was unique due to its use of physical representations as opposed to those strictly made of holograms . In use for nearly a millennium , the Planetarium was slightly expanded when a large statue of the slain Jedi Master Qui - Gon Jinn was erected in a small rotunda off the main chamber . After the three years of fighting that made up the Clone Wars , the Temple was invaded and routed by Darth Vader and the 501st Legion of the Grand Army of the Republic . The Planetarium was badly damaged and left in ruins , a testament to the might of the resurgent Sith Lords . Nearly two decades after the Jedi Order was exterminated , the Galactic Empire maintained a small force at the Temple ' s entrances . Stationed within the Planetarium were several stormtroopers and Purge trooper s capable of dealing with any Jedi who might attempt to enter the complex . In search of clues to his heritage , the former Sith assassin Starkiller entered the Temple ' s Planetarium and began to decimate the troopers there . While the room sustained even more damage , Starkiller ' s visit was brief and the room returned to its dormant state . Untouched throughout most of the Galactic Civil War , the Planetarium would eventually be destroyed when the five spires of the Temple collapsed during the catastrophe with the " Lusankya " and were cleared away . While the Temple was rebuilt by the order of the Galactic Alliance , it is unknown if the Planetarium was restored in the structure ; though the old blueprints were followed extremely closely with only minor changes . Layout . Located on the first floor of the Tower of First Knowledge , the Planetarium was situated off of the Spire ' s main entrance . Accessed via a hall that leading from the left side of the Spire Entrance the room wrapped around nearly a quarter of the central shaft that made up the heart of the tower . A long windowed hall , the center of the room was dedicated to the massive repulsorpad and holoprojector that created the planetary display . Several smaller bronzium globe orbited a larger central one with small holo - planets and other satellites buzzing around . Along the inner wall of the main space were balconies which displayed statues and artifacts of the Jedi Order ; expansive bas - reliefs were hung under the balcony ' s banister . Heritage tapestry hung from the vaulted ceiling , and large tablets declared the Jedi Code . Sunken areas near the windowed exterior wall were littered with podiums upon which busts of some of the Order ' s greatest minds rested , along with vases and urns collected from across the galaxy . Meditation benches were stacked neatly in areas for use by Jedi wishing to focus on the energies in the chamber . At the end of the hall was a raised rotunda filled with stained - glass windows ; a towering statue of Master Qui - Gon Jinn was erected in the center of the room . Immediately before the rotunda was an low , wide - mouthed access portal which led to a narrow hall that winded around the central shaft , ending in a balcony overlooking the open space .
