ENCYCLOPEDIA GALACTICA Edition 428193 - Earth English EGO 0602-00911069601: Summary EGO 0602-00911069601 is the twelfth satellite of EGO 0602-00911069544 - a fourteen (14) Jovian mass brown dwarf informally named 'Freya' - and the sixth life bearing world of 'Freya's Necklace'1. This world rotates with an axial tilt of 11.2 degrees2 and period of 63442 sec (0.73 days). Its orbital path is a 0.012 eccentricity ellipse inclined to 21.0 degrees, mean distance of 4.21 million km with a 14.8 day period. This body has no recognized common name either formally or informally.3 The satellite is a terrestrial like object with a mass of 0.64 Earths, density of 7.7 g/cm3 and diameter of 9820 km - making it the fourth largest satellite in the Freya system. The interior consists of a small solid nickel-iron inner core surrounded by a liquid iron outer core which is in turn covered by thin semi-molten silicate mantel. Combined with the short rotational period, these conditions produce a planetary magnetic field which is 44% more intense than that of Earth. Surface structures like the equatorial rift also show strong evidence of newly active plate tectonics. 56% of the surface is covered in liquid water consisting of shallow fresh water seas and very low saline oceans averaging 1130 m in depth and no deeper than 1410 m. Land masses consist of barren terrain heavy with silicates and iron oxide (hematite) creating the reddish hue. Highest peak is in the southern hemisphere at 10.2 km above sea level. On average, 90% of atmospheric mass extends to 13 km above sea level with a 17% variance from pole to equator. Composition includes 87.2% nitrogen, 11.4% oxygen, 1.1% water vapour, 0.2% methane and other trace materials including carbon dioxide and argon. Surface pressure at sea level averages at 81.9 kPa. Unexpectedly high for existing atmospheric composition and object mass. For the exception of some simple land based plant life close to the shorelines, all native life forms are concentrated in the oceans. It is hypothesized that this is due to the single helix heredity encoding mechanism4 for life forms on this satellite. This mechanism is useful for quick replication of genetic information which leads to increased frequency of mutation and faster evolution. However, there is less means for error correction and great susceptibility to outside effects like a strong planetary magnetic field. A line of cell division becomes nonviable more quickly and life forms can not adapt. In the oceans it is a different matter as natural selection has developed a biodiversity in the order of millions of species. Life forms range from simple molecular viral-like structures to complex organisms with differentiated internal organs, endoskeletons and central nervous systems. Some forms are photo consuming and produce molecular oxygen as a byproduct. This is accepted to be the primary source of oxygen in the satellite's atmosphere. Another characteristic of note are the large migratory waves that traverse most bodies of water. They are easily visible from space as they rise as much as 165 m and measure over 100 km across. These phenomena are not tsunami or any other common type of fluid wavefront. Curiously, these waves will always change course or disperse before impacting on a coastline. They also contain a much higher concentration (4200 times) of photo consuming microbial life forms than in the surrounding waters. It is unknown whether the waves attract the microbes or the microbes themselves somehow influence the wave formation. No technical civilization or any evidence of a civilization ever existing.
