Sol (aka The Sun or Helios) was the common name for the star that formed the Sol system, where the planet Earth is located. It is a main sequence star of the spectral class G2V with an age of circa 4.5 billion years and will at least shine for another five billion years.

The Human scientist Galileo Galilei was found guilty by an inquisition because of his teachings that Earth orbited the sun. (DS9: "In the Hands of the Prophets")

In February of 2152, Captain Jonathan Archer pointed Sol out to Keyla in the Risan night sky. (ENT: "Two Days and Two Nights")

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 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")

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. (Star Trek IV: The Voyage Home)
