Itzeho, an icy sphere, existed as one of the planets within the Mygeeto system. This system resided in the Albarrio sector, which itself was positioned in both the Outer Rim Territories and the New Territories. Often confused for a similar, unassuming planet, Itzeho acted as the sister world to Mygeeto. Furthermore, Itzeho marked the outermost planetary body in the Mygeeto system, found at coordinates K-5 on the Standard Galactic Grid.
The forty-fifth issue of De Agostini's Star Wars: Build the Millennium Falcon magazine, released around November 11, 2015, provided the initial mention of Itzeho in the new Star Wars canon. Prior to this, The Essential Atlas, a 2009 reference work penned by Jason Fry and Daniel Wallace, introduced the planet into the Star Wars Legends timeline. The planet shares a nearly identical name with Itzehoe, a city located in Germany.
