Sol system The Sol system ( also known as the Terran system and Earth ' s system ) was an inhabited planet ary system located within a stellar cluster . This system was located in Sector 001 ( the Sol Sector ) , a region of space in the Alpha Quadrant . This was the capital system of the United Federation of Planets . Location . The Sol system was located less than ninety light year s from the Qo ' noS system , a system in the Beta Quadrant . This system was located at the boundary line between the Alpha and Beta Quadrants . ( ; ; ) Solar system maps . In the late 19th century , the inner system was depicted on a German map of the inner system . ( , " opening credits " ) In 2254 , the inner system was depicted on a map , which was stored in the library computer . This was one of the records scanned by the Talosian s . ( , " production art " ) In 2267 , " Chart 14A : The Sol System " , which was stored in the " Enterprise " library computer , was a map of the Sol system . This chart was scanned by the probe " Nomad " in Auxiliary Control . ( , " production art " ) Star charts . In the 2270s , the location of Sol , and its largest planet Jupiter , was labeled on a neighborhood of astronomical objects , which was stored in the " Enterprise " library computer . This was one of the records scanned by " V ' ger " . ( , " production art " ) In 2293 , the location of Sol was labeled in a map of the Milky Way Galaxy . This map was on a wall of Captain James T . Kirk ' s quarters aboard the . ( , " okudagram " ) In 2364 , the location of Sol was labeled in a star chart , which showed the distance of this sun to neighboring stars in light years . This record was stored in the library computer . The Portal of Outpost 63 scanned this record that year . ( , " production art " ) Physical characteristics . The system consisted of its primary Sol and nine planets . An separated the system into an inner system and outer system . The inner system had four terrestrial planets : , Venus , Earth , and Mars . The outer system had four gas giant s and one terrestrial planet . The gas giants were Jupiter , Saturn , Uranus , and Neptune . The sole terrestrial planet in the outer system , and outermost planet in the Sol system , was Pluto . ( ; ; ; ) History . Approximately four billion years ago , an ancient species of humanoids injected genetic material into the primordial soup on Earth . Five hundred million years later , life began on Earth . ( ) Approximately sixty - five million years ago , a comet collided with the planet Earth . With this mass extinction event ending the dinosaur ian era , mammal s rose to prominence . One of those mammalian species , Human s , forged a civilization on their home planet . Starting in the mid - 20th century , Humans began the process of exploring and colonizing their home system . By the late 24th century , there were Humans living on Venus – which was being terraformed into a M - class planet – on Luna , on Mars , and on the moons of Jupiter and Saturn . ( ; ; ) In 2370 , the Sol system was listed on the Deep Space 9 arrival roster as the point of departure for the USS " Hispaniola " . ( , " okudagram " ) In 2371 , a microscopic singularity passed through the system and exploded . ( ) The Borg maintained a transwarp conduit with an aperture less than a light year away from Earth . The conduit was collapsed by the in 2378 . ( ) " In an alternate timeline , all major inhabited planets and colonies in the Sol system were destroyed by the Xindi weapon . This ended when the crew sacrificed themselves to change the future by erasing interspatial parasite s from Jonathan Archer , allowing him to remain in command and find and destroy the weapon . " ( ) " In another alternate timeline , the entire Sol system was destroyed in a temporal explosion when Henry Starling took the timeship " Aeon " from the 20th century to the 29th century without properly calibrating the temporal matrix . This event nearly happened but was stopped when Captain Janeway manually fired a photon torpedo from " Voyager " at the " Aeon " as it entered the temporal rift , destroying it and killing Starling . " ( ) Appendices . Background information . A map of the galaxy created for " " was reused on a PADD in the film depicted the location of the Sol system . The PADD prop was sold on It ' s A Wrap ! sale and auction . Deep Space 9 ' s classroom featured a painting of four planets of the Sol system including Earth and Saturn earlier . ( ) The chart naming astronomical objects was from the " Star Fleet Technical Manual " . The chart naming stars within twenty 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 . Sol was a stop on the Alpha Centauri - Epsilon Eridani commercial route . According to " " ( Pg . 19 ) , although the Sol system is located in the exact corner of the sector and was thus divided equally among all eight sectors , it is considered to be in Sector 001 for purposes of celestial navigation . Similarity , while the Sol system is divided equally between the Alpha and Beta Quadrants , it is considered to be part of the Alpha Quadrant . According to " The Worlds of the Federation " , there was a tenth planet beyond Pluto . Apocrypha . The real - world debate on the status of Pluto as a planet was referenced in the novel " Before Dishonor " .
