TY44 was the name of one of a "string" of satellite-moons orbiting the planet Typha-Dor, located in the Uziel system.
Named for its coordinates, TY44 had a very icy terrain and its surface was covered with glaciers.
By 25 BBY, a surveillance outpost of Typha-Dor was located on this moon. Several of its resistance fighter-crew members were eliminated by the would-be invaders of their home planet, expansionist forces from Vanqor who sent in a saboteur to infiltrate the crew's operations and assassinate its members.
In 25 BBY, Jedi Obi-Wan Kenobi and Anakin Skywalker were sent to rescue the outpost's surviving crew members by the Jedi High Council at the request of the Galactic Senate.
