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. (TOS: "The Cage", Star Trek VI: The Undiscovered Country, production art, ENT: "Two Days and Two Nights") The location of Sol was also seen in a viewscreen chart displayed by the USS Enterprise-D library computer. (TNG: "The Naked Now", "The Last Outpost", "Datalore", "Conspiracy")
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. (TNG: "Where Silence Has Lease"; DS9: "In the Hands of the Prophets")
In April of 2153 as the Enterprise NX-01 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. (ENT: "The Expanse")
During the mid-23rd century on at least two accounts, the crew of the USS Enterprise used Sol to assist in a method of time travel known as the slingshot effect after they had been sent to the past. (TOS: "Tomorrow is Yesterday", "Assignment: Earth")

The viewscreen graphic on the bridge of the USS Enterprise from Star Trek II: The Wrath of Khan, 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.
This 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.
"The Explored Galaxy"
"The Explored Galaxy" was a map of charted space in the Alpha Quadrant. Sol was located between the Tholian Assembly and Romulus. Both locations were identified in DS9: "The Search, Part II", "Call to Arms" as being located in this quadrant. The chart, first seen chronologically in Star Trek VI: The Undiscovered Country, 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. These were TNG: "Conspiracy", "The Measure Of A Man", "The Emissary", "The Mind's Eye", "The Game", and DS9: "In the Hands of the Prophets", "Cardassians".
