Psi 2000

Psi 2000 was a Class P planet that disintegrated in 2266.

Prior to the disintegration of Psi 2000, a Federation survey team was dispatched to study the large gravitational shifts, which also resulted in large strings of water molecules and polywater, which in turn resulted in the Psi 2000 virus. The members of the survey team soon succumbed to the virus and quickly died when someone adjusted the environmental controls and they froze to death.

When the USS Enterprise arrived to collect the team several weeks later, they discovered that the whole team were dead, but the virus was also transferred to the Enterprise by Lieutenant Joe Tormolen. The virus quickly spread through the Enterprise crew, and in a state, Lt. Kevin Riley entered engineering and shut-down the warp engines, leaving the Enterprise stranded in orbit of a disintegrating planet. Thankfully, Lt. Commander Montgomery Scott was able to initiate a cold-restart of the engines and escape. (TOS episode: "The Naked Time" and novel: The Janus Gate: Present Tense).
