The planet is known for its extrem amount of Sparklium a precious material used as fuel for spaceships in the Pikmin series. Life can be found on the planet, the life-forms living on the Unknown Planet have much in common with those found on PNF-404.

Before the games
Many man made items can be found on the Unknown Planet but Shigeru Miyamoto said in an interview that the earth was supposed to be PNF-404 and the Unknown Planet is known to be a different planet, so either it was a human colony or the home to a species similar to humans.

Hey! Pikmin
After the events of Pikmin 3, Olimar is seen sailing in space inside his new ship, the S.S. Dolphin II, returning to Hocotate after his work, he try to warps to his home planet only to be greeted by an asteroid field located near the Unknown Planet. The ship try to avoid the asteroids but two of them hits the ship forcing it to crashland on the planet's surface. During the crash the Sparkilium tank leaked and all of the fuel was lost, Olimar is forced to find enough Sprklium infused item across the Planet in order to get back to Hocotate, luckily, the planet is also home to a colony of Pikmin (species)[Pikmin that will help the captain in his search. After retrieving all of the Sparklium needed, The S.S. Dolphin II notice that a key component of the Sparklium tank went missing and living the planet will be impossible without it.

Olimar find the component after a search across the whole planet, it was found by a Leech Hydroe that went berserk after finding it, the Captain and his Pikmin defeat it and retrieve the component allowing Olimar to leave the Unknown Planet.
