73,[2] also known as Sienar, was a snow-covered planet owned by Sienar Fleet Systems. One of many numbered worlds owned by the company, 73 was home to Sienar Test Facility 73.[2] An open road way ran from the test facility to elsewhere on the planet. In 4 BBY, a Sienar employee named Niya assisted Cassian Andor in stealing a TIE Avenger prototype on 73. During the heist, two TIE Advanced v1s were destroyed by falling debris as they chased Andor through an ice tunnel on the planet's surface.[1]
