Titan
Titan was an inhabited moon of Saturn. The dense atmosphere of Titan, which was toxic for Humans, was used for exceptional starship maneuvers. (; ; )

History 
In the 2140s, while on Titan as part of the Omega training mission with Captain Jonathan Archer,  encountered problems while on an extravehicular (EV) exercise. His EV pack froze up and he experienced nitrogen narcosis. However, Archer was able to convince Tucker not to remove his helmet while still unsheltered on Titan's surface. ()

In the mid-23rd century, sometime between 2234 and 2259, the Crestbrock mining collapse occurred on Titan. The AP 350 atmospheric processor saw its first deployment during the relief efforts. ()

In 2258, in the alternate reality, the crew of the  used the conditions on Saturn and Titan to help hide their ship from the sensors of the Narada. ()

In the 24th century, Titan was a major navigational reference in the Saturnian system and its orbit was part of the Academy Flight Range. Nova Squadron used Titan as a rendezvous point before beginning training maneuvers during preparations for Starfleet Academy's commencement exercises in 2368. They entered Titan's gravitational sphere, and then moved into a diamond slot formation before executing a low apogee turn around the moon in preparation for an illegal Kolvoord Starburst maneuver. ()

Titan was also a favored way point for pilots making the Jovian Run. A dangerous shuttlecraft maneuver sometimes performed by Starfleet pilots on this run was called Titan's Turn. ()

A research colony was established on Titan by Humans, consisting of habitats and a liquid hydrocarbon research base. In the post-Burn era, the colony, being fully self-sufficient, split off from Earth in circa 3089.

About a century later, there was an accident at the research base, which wiped out the tillable soil and destroyed a third of the habitats. With no long-range communications, Titan sent a ship to Earth asking for help; the ship was fired upon and destroyed by Defense Force ships. Believing that Earth had left them to die, the colonists became dilithium raiders, targeting Earth ships and grabbing what dilithium they could. In 3189, with Captain Saru of the  acting as a mediator, the two sides agreed to a truce and began working on the terms of a deal. ()

Val Sasha grew up on a Titan colony where she had never seen a non-Human before. ()

By 3190, Titan had re-joined United Earth to form United Earth and Titan. ()

When the Sol system was threatened by the Dark Matter Anomaly later that year, the entire population of Titan was evacuated by the . The moon was subsequently badly hit by the DMA, but Earth sent swift aid. ()
