Age: 2-10 billion years

Diameter: 10,000 - 50,000 km

Location: Hot, Ecosphere, and Cold Zones

Surface: Temperatures can exceed 500K

Atmosphere: Turbulent, saturated with toxic chemicals and thermionic radiation

Life-Forms: Mimetic (Delta Quadrant)

Found in all star zones, Class Y planets are extremely inhospitable worlds. When encountered by scouting vessels they should be given a wide berth. Surface temperatures can exceed those of volcanic worlds, being in the range of 300 to 500 C. The atmosphere contains toxic unbreathable gases, and at certain geological locations emit lethal levels of thermionic radiation.
