"My God, Carol. Look at it."
– James T. Kirk to Carol Marcus, 2285 (Star Trek II: The Wrath of Khan)

The Genesis Planet was an uninhabited planet located in the Genesis sector, a region of space in the Mutara sector. When the Genesis Device exploded, which resulted in the destruction of the USS Reliant, the planet was formed from the coalescence and cooling of the gas and dust of the Mutara Nebula. The explosion occurred at the conclusion of a fierce battle between Khan Noonien Singh and Admiral James T. Kirk in 2285. (Star Trek II: The Wrath of Khan; Star Trek III: The Search for Spock)


Formation of Genesis

Genesis' creation

Following the initial creation of the planet, Captain Spock's photon torpedo casing was launched towards it, following his funeral service. Because gravitational fields were in flux, his casing soft-landed on the planet's surface. (Star Trek II: The Wrath of Khan; Star Trek III: The Search for Spock)

The Genesis Planet immediately became a galactic controversy, and Starfleet declared it off limits until the Federation Council could decide what to do. In the meantime, the USS Grissom was dispatched with a scientific team that included the planet's co-creator, Dr. David Marcus, to carry out a thorough investigation. While exploring the planet with Saavik, Marcus admitted that he'd used protomatter to complete the Genesis matrix. The unstable and dangerous properties of the protomatter were a contributing factor in the planet's rapid aging and instability.

Genesis planet destruction

Genesis' final sunrise

A battle occurred in orbit during the final degradation of the planet in which both the USS Grissom and the USS Enterprise were destroyed and a Klingon Bird-of-Prey HMS Bounty was commandeered by Admiral Kirk and his remaining crew. (Star Trek III: The Search for Spock)

Three months later, in an angry tirade directed at the Federation Council and the Federation President, the Klingon Ambassador alleged that this planet would have housed a secret base from which Kirk would have launched a genocidal campaign using the Genesis Device against the Klingons. His allegations were debunked by Sarek, who pointed out that Genesis was named for creation of life and that the Klingons shed the first blood in trying to possess its secrets.

Initial scans of the new planet, from the Grissom, indicated several fascinating revelations, including "all the varieties of Earth's land and weather, within a few hours' walk," according to Dr. Marcus.

  • Sector 1: Had foliage in fully-developed state of growth; temperature: 22.2 °Celsius
  • Sector 2: Had desert terrain. Minimal vegetation; temperature: 39.4 °Celsius
  • Sector 3: Had subtropical vegetation; temperature decreasing rapidly, indications of snow

Diverse ecology

The same effect that hyper-evolved the plantlife on the planet seemed to have had the same effect on microbes on the surface of the burial photon torpedo that soft landed on the planet shortly after it was created. The microbes evolved into multicellular organisms in a very short period of time.

Unstable protomatter, used in the matrix's construction by David Marcus in his haste to complete the Genesis Project, caused the ecosystems it had created to become dangerously erratic. This instability manifested itself first in an accelerated rate of growth, then in micro-climatic upheavals. Instead of flourishing, the planet began to experience heavy geologic activity that resulted in the entire surface becoming molten. (Star Trek III: The Search for Spock)


Background information[]

This planet's quadrant of origin is inferred based on the position of Spock's last known position in the Mutara sector (DIS: "Light and Shadows") as seen in the star chart appearing in the Star Trek: Discovery episode "An Obol for Charon".

A lot of Genesis space microbes were sold off on the It's A Wrap! sale and auction on eBay. [1]

The Star Trek Encyclopedia, 4th ed., vol. 1, p. 301 classified the Genesis Planet as a class M planet.


In the Genesis Wave series, Captain Jean-Luc Picard reads a report on the Genesis project which speculates that the Genesis Planet collapsed because it was formed from a nebula rather than the protomatter being the automatic cause of the failure, suggesting that Genesis would have worked if it had been fired at a planet as it was originally intended.
