STAR CHART: PLANETS -
PLANETARY CLASSIFICATION - Q, R, S-T

The Class-Q example of the Genesis Planet mentioned in the above STSC illustration is actually noted in Encyclopaedia as a Class-M world. It is formed from the gaseous matter in the Mutara Nebula by the Genesis Device (a short-range torpedo intended to test the Project Genesis terraforming process) when the Device is prematurely activated after being stolen by Khan Noonien Singh, in 2285. The planet appears to have an almost idyllic environment, but it is later learned that dangerously unstable protomatter used in the Genesis process caused the planet itself to become dangerously unstable and eventually explode. [Star Trek III: The Search for Spock] In [#89 The Omega Directive], Janeway refers to those events: "Captain's log, supplemental. Computer, encrypt log entry. We're approaching the star system where we believe we'll find Omega. I have to admit, I have never been this apprehensive about a mission. I know how Einstein must have felt about the atom bomb or Marcus when she developed the Genesis device. They watched helplessly as science took a destructive course. But I have the chance to prevent that from happening. I just hope it's not too late."

The Class-R example mentioned in the above STSC illustration refers to Dakala, a rogue planet featured in [Enterprise: Rogue Planet]. It supports a diverse animal population. When Ensign Mayweather queries that the planet should be frozen solid, T'Pol explains that hot gas is vented from the planet's interior, and that most of the life forms are concentrated in those areas due to, Captain Archer deduces, oases; there is no evidence of humanoid life, but they discover a ship on the planet surface. Chief engineer Tucker comments: "Maybe they want to be left alone. A single ship on a dark planet? Maybe they're on their honeymoon."
