aka Sol IX
Pluto is the ninth planet in the Sol system, which can be found at HyperSpace coordinates 175.2 : 145.0.
It is a Pellucid World, and has 125 Resource Units to mine.
Pluto is not only the furthest planet from the sun (most of the time), but it is also the smallest, coldest, has the lowest gravitational pull, and has the most elliptical orbit of all the planets. It is believed that Pluto was actually a passing body in space that passed close enough to the sun to be captured into its present orbit.
The Spathi captain Fwiffo, last of the Ur-Quan's Earthguard forces, is found hiding here in his Eluder vessel StarRunner.
