The Alpha Omicron system was a planetary system with at least seven planets and an asteroid belt.

The system's asteroid belt was inhabited by a spaceborn race.

This system was uncharted by the United Federation of Planets until 2367, when the USS Enterprise-D briefly stopped there on the way to the Guernica system. The starship went into the system to investigate an asymmetrical field of intense energy that was coming from near Alpha Omicron VII. (TNG: "Galaxy's Child")
