Special Containment Procedures: Due to the nature of SCP-9900, it is currently impossible to be contained. All proof of the existence of SCP-9900 must be removed from the wider scientific community (i.e. outside of the Foundation’s archives). If any new discovery is made about SCP-9900, all known documents must be confiscated or destroyed, and the originator of the discovery must be taken into Foundation custody (see addendum A). Any other individual who has come into contact with the information must be amnesticized.

Description: SCP-9900 designates a planet with anomalous properties that exist within the trans-Neptunian region of the Solar System, which astrophysicists have dubbed “Planet Nine”. It is approximately five times the mass of Earth and is composed of 26% water, 20% oxygen, 10.3% methane, 5% calcium, 2.6% aluminum, [DATA EXPUNGED]. It orbits between 11 billion kilometers and 125 kilometers from the Sun.
SCP-9900 is currently known in the wider scientific community as being a purely hypothetical object, as all proof of its actual existence has been erased. George Forbes postulated the existence of two trans-Neptunian planets in 1880, one of which was designated SCP-9900.
SCP-9900’s first known record of observation was on ██/██/██.
The planet is inhabited by humanoid shape-shifting creatures who take the form of all individuals and objects that come in contact with the planet’s surface The creatures mirror perfectly the outward appearance of the individuals or objects, but the actual composition of their bodies is silicone, aluminum, [DATA EXPUNGED]. The creatures are extremely violent and will attack all foreign individuals and objects on sight. The planet's soil is capable of producing perfect replicas of all foreign objects, organic or inorganic. The replicas fall back into dust as soon as the foreign object escapes the atmosphere of the planet. They are extremely violent and will attack all foreign individuals and objects on sight. SCP-9900 is not habited by any living organism.
