Pluto

A Class-C planetoid,^[1] Pluto alternated between being considered a planet and a planetoid ever since its discovery in the mid-20th century:^[5] in 1996, Pluto was depicted as the ninth planet in the Sol System on a poster in Rain Robinson‘s office at Griffith Observatory;^[3] in 2367, the U.S.S. Enterprise NCC-1701‘s computers showed a map to Nomad, depicting Pluto as the ninth planet in the system.^[1] In 2292, the maiden voyage of the U.S.S. Enterprise NCC-1701-B was planned as “a quick run around the block,” taking the ship from Earth, out past Pluto, then back to the inner system; a distress call from the S.S. Lakul, however, necessitated a change of plans.^[2] Pluto had a diameter of 2300 kilometers, a surface temperature of -236°C, a rotation of 6390 days, and gravity of 0.07 g. Located 5.9 billion kilometers from Sol, it took 248.5 Earth years to complete one orbit. Pluto had one moon, Charon, which was nearly as large as Pluto itself.^[4] In the EU timeline, Pluto was destroyed during a Borg invasion of the Sol System in 2381.^[5]
