Sol

Classified as a yellow dwarf star, Sol was the primary for the Sol system. This system was located in a stellar cluster in Sector 001 (or Sol sector) of the Alpha Quadrant.

The location of Sol in the Milky Way Galaxy was depicted on a Federation star chart in 2293. Sol was located near Tau Ceti, Alpha Centauri, and Sirius. (,, production art, ) The location of Sol was also seen in a viewscreen chart displayed by the USS Enterprise-D library computer. 

History
For centuries, Humans believed that Sol revolved around Earth. When the scientist Galileo Galilei publicly challenged this belief in the early 17th century, by teaching that the opposite was true - that Earth revolved around Sol, he was tried and convicted by an inquisition. The inquisition ordered that his books be burned. 

In February of 2152, Captain Jonathan Archer pointed Sol out to Keyla in the Risan night sky. 

In April of 2153 as the was returning home due to the Xindi attack on Earth, Ensign Travis Mayweather notified Captain Jonathan Archer that Sol could be seen on the ship's viewscreen. 

During the mid-23rd century on at least two accounts, the crew of the USS Enterprise (NCC-1701) used Sol to assist in a method of time travel known as the slingshot effect after they had been sent to the past. 

In 2254, Sol was seen on a map depicting the inner Sol system. This map was scanned by the Talosians. 

Three years later, Sol was seen on a chart depicting the Sol system. This map was scanned by Nomad. 

In the year 2286, the crew of "HMS Bounty" used the "slingshot effect" to travel to the year 1986, and once again in that year to return to 2286.

Background information
The viewscreen graphic on the bridge of the USS Enterprise (NCC-1701) from, was taken from page T0:02:07:02 of the Star Fleet Technical Manual by Franz Joseph. Many of the names for astronomical bodies were unique to this book.

The star chart naming stars within 20 light years of Sol was drawn by Rick Sternbach for the Star Trek Spaceflight Chronology in the late 1970s. Found on page 77, this chart showed Earth commercial and exploration routes after the use of warp drive began.
