Tycho IV

Tycho IV (or Tychos IV) was a planet located somewhere in the space of the galaxy's Alpha or Beta Quadrants, the fourth planet in orbit of the Tycho star system.

History and specifics

Amongst the many elements or matter that have been detected on the planet include dikironium, dilithium, and dioramium. (TOS comic: "The Ashes of Eden")

In the year 2257, the planet was visited by the Constitution-class Federation starship, USS Farragut. While landing parties were surveying the planet, they were attacked by a dikironium cloud creature. Following this attack the creature proceeded into space and entered the Farragut, where it killed 200 crewmembers, including Captain Garrovick.

For many years, James T. Kirk believed that, had he not hesitated in firing phasers at the creature before it entered the ship, that all their lives could be saved. However, it was revealed in 2268 during an encounter between the creature and the Starfleet ship USS Enterprise, that the creature was impervious to phaser fire. (TOS episode: "Obsession", TOS - My Brother's Keeper novel: Constitution)

It was a case of poetic justice when the creature was destroyed by Kirk on the planet in 2268 with a large antimatter device which was detonated when the creature tried to attack it. (TOS episode: "Obsession")

The TOS novelization & comic adaptation: The Ashes of Eden presents a simulation of an alternate mission to Tycho IV in a different manner than what was described in My Brother's Keeper: Constitution. In this version, Kirk and Androvar Drake beamed down to the planet to locate the creature, and after hesitating to fire, the creature proceeded to destroy the Farragut. TOS - The New Voyages short story: "Ni Var" called the world "Tychos IV".
