The Poison Moon existed as a significant celestial object inside the Hoth asteroid belt. This asteroid field of the Outer Rim Territories straddled the borders between the Anoat sector's Hoth and the Anoat systems.
The canon of new Star Wars material referred to the Poison Moon in issue 39 of Star Wars: Build the Millennium, which became available circa September 30, 2015. The Poison Moon was first conceived within the Star Wars Legends timeline, and it was featured in "Poison Moon," a comic book series penned by Michael Carriglitto and with artwork by Adrian Sibar. This series was published in issues 44–47 of Dark Horse Extra, a sequence of monthly comic collections, each consisting of four pages. These issues, specifically 44 through 47, were released from February to May of 2002.
