Gault was an inhabited planet. This was the home of a Federation colony with a sparse population of no more than 20,000 inhabitants. It was widely regarded as a "farmworld". (TNG: "Heart of Glory"; DS9: "Let He Who Is Without Sin...")
In 2346, Sergey and Helena Rozhenko lived on Gault with their son, Nikolai; the following year, their adopted son Worf went to live there. One of the secondary schools on Gault had a soccer team which Worf captained in 2353 at the age of thirteen. Worf headed a ball into the goal and accidentally killed the opposing player named Mikel.
