An inhabited planet near Earth, home of the Draylaxians, which is a regular stop for human freighters in the 22nd century and is mentioned several times in Star Trek: Enterprise.
Draylax is the homeworld of the Draylaxians and one of the first alien worlds with which Earth traded regularly. It is never seen on screen, but it is part of the background of the Enterprise era.
In Broken Bow, Travis Mayweather, who grew up on the freighter Horizon, says he has been there and jokes about its people. Fortunate Son establishes that cargo ships work a run between Draylax and Vega Colony, and its freighter captain praises Draylaxian whiskey. In Desert Crossing, Archer uses the name in a geography game to keep an exhausted Trip Tucker awake.
The planet keeps turning up on star charts in later series, among them Strange New Worlds, Picard and the Discovery episode The Examples, which shows that it is still marked on maps of the Federation's neighbourhood in the 32nd century.
