Star system image.
From1930 to2006, Pluto was considered the 9thplanet in theSolar System, at which point it was reclassified as adwarf planet. Pluto's status among astronomers would shift between planet and dwarf planet several times between the21st and24th centuries (TNGnovel:Before Dishonor).
The planet was named after theRoman god of the underworld. The planet was approximately a fifth of the size ofLuna, and was comprised mainly of rock and ice. It had an eccentric orbit that brought it closer to theSun than the planetNeptune for a 20-year period during its revolution around the Sun.

This left tense relations between theTerrans and the Orions. (FASA RPGmodules:The Federation,The Romulan War;STreferences:Spaceflight Chronology,The Worlds of the Federation)

In2273,Nyota Uhura adjusted thegravity to Pluto level, about 0.06 standard, in theUSSEnterprise’s variable-gravitygym. She considered it challenging to function in what deceptively felt likezero gravity. (TOSnovel:Ex Machina)

TheStarfleet Archives Annex was on Pluto. It was chosen as a long-term secure location for keeping historical data because Pluto's frozen core precluded geologic activity and it would survive afterSol went nova in the distant future. In2374, theMirror UniverseJames T. Kirk penetrated security there to accessCaptainJames T. Kirk’s logs from his firstfive-year mission. (TOSnovel:Dark Victory)
