ENCYCLOPEDIA GALACTICA Edition 428193 - Earth English EGO 0602-00911069604: Summary EGO 0602-00911069604 is the fourth satellite of EGO 0602-00911069544 - a fourteen (14) Jovian mass Y-dwarf or 'brown dwarf' informally named 'Freya' - and seventh life bearing world of 'Freya's Necklace'.1 Mass 0.36 Earths, density 2.9 g/cm3, diameter 4173 km.2 Rotational axis tilt is 0.4 degrees with rotation captured to the orbital period of 23415 seconds (0.27 days).3 Orbital eccentricity 0.02, inclined 13.0 degrees, and mean distance of 291 thousand (103) km. Magnetic field is 5% the strength of Earth's. This body has no recognized common name.4 In composition the interior consists of a semi-solid silicate mantle surrounding a molten silicate core - 18% nickel-iron intermix. Less than one (1) per cent of the surface is covered by any metabolic supportive media such as water. The surface is young, barren terrain of silicate igneous rock heavy with iron and copper oxides creating desaturated orange to green hues.5 Highest point is a tidal jet in the northern hemisphere at 917m. Ninety (90) percent of atmospheric mass extends 3km above ground with 15% variance from pole to equator. A consequence of the satellite's quick rotation and proximity to Freya's gravity well. There is a variance of 4% from near to far sides. Composition: 55.2% nitrogen, 40.4% methane, 3.1% carbon dioxide, 0.8% oxygen, 0.2% trace materials including water vapour.6 Surface pressure averages 31.1 kPa. The moon's close, eccentric orbit about 'Freya' subjects it to intense gravitational flux. The induced compression generates violent seismic activity apparent in the number of volcanic jets and fractured surface features - no evidence of plate tectonics. The release of such energies can abruptly and permanently change local environmental conditions on the surface. The thermoconsumptive7 life forms are at a constant disadvantage as organisms do not have sufficient time to adapt to habitats before they change. Biospheric dominance is sparse and congregated close to the poles where there are fewer jets with temperatures sufficiently low to allow small lakes of methane infused water to form. Life persists at the molecular and cellular levels. Multicellular life is not known to exist, though it is observed that differing cellular forms congregate together into symbiotic communities. The communities themselves display mitosic characteristics in that they grow and divide to create daughter communities. Through varying the components of their memberships, new daughter communities dynamically re-adapt to their local habitat. Heredity is dispersed through the local environment and not maintained in genetic lines. Organisms consume phyletic information from materials in suspension to spawn offspring. Nucleotide-like structures and minerals (providing a crystalline framework) are obtained from surface contact, liquid media and atmospheric aerosols. Organisms similarly replicate and deposit successful trait templates back into the environment. Thus creating a habitational library of characteristics within which organisms assemble the qualities required for the next generation.8 Qualities suitable for survival in an environment that is subject to rapid change.
