Gamma Canaris region

The Gamma Canaris region was a remote region of space. This region, located near the Epsilon Canaris system, was in the Alpha Quadrant. There was an asteroid belt in the region, that consisted of approximately 7,000 bodies of sizes running from types A to N. 34 percent of which had atmospheres of types H to M.

The location of Gamma Canaris N, a planetoid in this region, in the Milky Way Galaxy was depicted on a Federation star chart in 2293. (, production art)

History
In the early 22nd century, a non-corporeal lifeform native to this region, known as the Companion, discovered the disabled warp ship of the Human inventor of Earth's warp drive, Zefram Cochrane. The entity brought the ship and its pilot Cochrane safely down to its homeworld, a planetoid in the asteroid belt. The Companion rejuvenated the 87 year old inventor and terraformed the planetoid to sustain Cochrane's life.

In 2267, while transporting the terminally-ill Commissioner Nancy Hedford from Epsilon Canaris III to the USS Enterprise (NCC-1701), shuttlecraft Galileo was pulled off course by the Companion and forced to land on its homeworld. Cochrane had told the entity that he would die of loneliness if he didn't have contact with other humans. The Companion merged with Commissioner Hedford moments before her death and Cochrane remained with her on the planetoid. James T. Kirk promised Cochrane that he would not tell Starfleet that they had discovered him or of what had happened on the planetoid. 

In the faked computer records of Commander Keiran MacDuff, it was stated he was born in Gamma Canaris N on September 27th, 2334. 

Background

According to Gold Key Comics Star Trek issue 49 A Warp in Space, Gamma Canaris N was the name of Companion's homeworld. . This contention was supported by Startrek.com.

"The Explored Galaxy" was a map of charted space in the Alpha Quadrant. Gamma Canaris N, a planetoid in this region, was located between the Tholian Assembly and Romulus. Both locations were identified in as being located in the Alpha Quadrant. This chart, first seen chronologically in, was also seen in several Star Trek: The Next Generation and Star Trek: Deep Space Nine episodes set in the 24th century, from the year 2364 to 2370.
