Lizard-7566-N (Thrid name: K'lovekt meaning "god's eye") is the second of the four gas giants and the fourth planet orbiting the star Lizard-7566-A (L7566A by the humans and Lizards) in the Lizard-7566 System. Slightly larger and considerably more dense than Jupiter, Lizard-7566-N has no rings and has eighty-six moons, the most notable being Yasiyykk.
Lizard-7566-N exerts strong gravitational and magnetic influence on Yasiyykk which contributes to the dramatic geological and morphological elements on Yasiyykk's surface, called flux deposits.
Lizard-7566-N is similar to Jupiter. But unlike that planet, which is located in the outer reaches of the Solar System, Lizard-7566-N orbits Lizard-7566-A at a distance comparable to Earth's orbit around the Sun. Because Lizard-7566-N formed in a much higher-temperature environment than Jupiter, it is composed of a much larger proportion of helium and carbon dioxide and has a much greater mass for its size. It also has a proportionally larger liquid metallic hydrogen core, an iron central body, and produces a far stronger and more extended planetary magnetic field.
Originally, the planet was named "Hydra", after a serpent in Greek mythology, however the name was later changed to its current one.
Overview
Visually, Lizard-7566-N resembles a slightly larger, green and blue version of Jupiter, with less prominent bands and a large vortex storm. Unlike other gas giants, Lizard-7566-N has no visible rings and to date, no trace of a ring system has been found.
At 114,050.197 miles in diameter, Lizard-7566-N is slightly larger than Jupiter and considerably more massive. Its magnetic field, and thus its core, rotates in 9.7 hours. The visible surface features rotate more slowly, ranging from 10.1 to 10.6 hours, depending on latitude. Lizard-7566-N has more prominent banding than Jupiter, although not as spectacular. Still, Lizard-7566-N has a vortex storm far exceeding Jupiter's "Great Red Spot" in turbulence. It also has an unusual internal structure and complex magnetic interactions with its inner satellites.
Lizard-7566-N appears to be a typical gas giant with a typical composition. Like most planets, it started condensing from the primordial stellar nebula. Lizard-7566-A's system happened to be very rich in the heavier elements, particularly iron and lead. Also, having formed closer to its sun, it has far less hydrogen because the higher temperature increased the speed of the lightest gas atoms preferentially, allowing them to escape the star's vicinity. The stellar wind also contributed to removing the lighter elements, blowing them farther outward.
Auroral activity is near-continuous and intense enough to be visible in daylight. When magnetic flux tubes form and link to various satellites, they too display brilliant auroral bands in the moons' polar regions where the tubes' flux joins the global ones.
As with all gas giants (especially gas giants close to the parent star, as with Lizard-7566-N), this planet is surrounded by a lethal halo of charged particles (the radiation belts around Lizard-7566-N are more energetic than the belts surrounding Jupiter); the innermost moonlets of Lizard-7566-N have reported radiation in excess of 8,100 rem per day (Io receives 3,200 rem per day), which is aggravated due to the higher metallicity in the planets' internal composition. Yasiyykk resides just outside the main radiation belts of Lizard-7566-N, except for a week, when rotating along the night side of Lizard-7566-N. At that time, the planet is shrouded at night in a shimmering aurora and receives a scourge of radiation.
Yasiyykkan life has evolved to not be affected by strong ionizing radiation, but humans on Yasiyykk routinely take iodine supplements and seek protection during radiation storms; even then, incidences of radiation-related sicknesses absorb a significant part of medical treatments for personnel stationed on Yasiyykk.
Lizard-7566-N can be seen in the sky on Yasiyykk. Depending on where the moons are in their orbits, Yasiyykk may also have two or even three moons in its sky at once. Depending on L7566A's position, Yasiyykk and the other large moons cast dark shadows on Lizard-7566-N.
Atmosphere
Because it formed in a higher-temperature environment, Lizard-7566-N has far less hydrogen and more helium and CO2 in its atmosphere than most gas giants: fourty-four percent hydrogen, fourty-four percent helium, and eleven percent carbon dioxide, compared to Saturn's ninety percent and ten percent. Since helium is about twice as dense as hydrogen, Lizard-7566-N is much more massive than Jupiter and thus has increased gravitational compression sufficient to produce a liquid metallic hydrogen center twice as large. The remaining one percent of the atmosphere is mainly composed of the gasses methane, ammonia, hydrogen sulfide, and water vapor.
There are minor amounts of compounds that are chemically reactive and therefore require a continual renewal mechanism. These compounds include acetylene, carbon monoxide, ethane, germane, methyl acetylene, phosphine, and propane. They are produced by high-temperature chemical reactions deep in the planet's interior, upper atmosphere energetic reactions from stellar ultraviolet photons, high-energy particles from the radiation belts, and atmospheric lightning discharges.
This chemical "stew" is stirred by convection currents and shearing-force winds produced by the planet's rapid rotation. The result is a brilliant display of an ever-changing pattern of colored cloud belts and rotating storms.
Internal Structure
Beneath the liquid droplet clouds that make up its visible "surface", Lizard-7566-N's atmosphere gradually thickens as its temperature and pressure build up from gravitational compression. When the pressure reaches about one-hundred and thirty-six megabars (approximately 134,221,564 pounds per square inch, which is almost one-hundred and thirty-five million times Earth's sea level atmospheric pressure) and the temperature reaches about 6,000 K (10,340 °F, slightly hotter than the surface of the Sun), hydrogen undergoes a phase change to its metallic form. The size of the liquid metal portion is about three-quarters of the planet's total diameter. This feature is common to all but the smallest gas giants.
Continuing downward, there is a central core of molten iron, surrounded by a thin "jacket" of lighter, rockier material. Large amounts of iron are not commonly found in gas giants as they have mainly rocky cores.
Lizard-7566-N has an intense internal heat source that results from the gravitational energy released during the contracting of the gases from which it is formed. Additionally, as hydrogen and helium were compressed, they changed from gases to liquids. This released their latent heat (also called the "heat of vaporization", which is the amount of energy it takes to evaporate a liquid into a gas). Finally, some of the helium that dissolved in the metallic hydrogen core condensed out & moved downwards, converting its gravitational potential energy into heat via friction processes.
Magnetic Environment
Lizard-7566-N's rotation and its internal heat sources produce circulating convection flows in its liquid center. These flows carry entrained electric currents that generate an extremely powerful magnetic field. The liquid iron core at the center of the liquid metallic hydrogen exerts a synergistic effect and intensifies the magnetic field far beyond those produced by conventional gas giants. This magnetic field rotates with the planet. It serves to trap charged particles (electrons, protons, and ionized atoms and molecules) into various radiation belts that encircle the planet.
Satellite System
Lizard-7566-N is said to have eighty-six moons. Dakishk is the innermost moon, followed by Uakkyshk. The third is Ackyym, but the fourth is Yasiyykk.
Nuukkkykk is one known moon, and Jukkysk orbits beyond Nuukkkyk, although their exact placements are unknown.
The two outer moons are known to orbit in a different direction from all the others.
Since Lizard-7566-N's orbit lies in L7566A's habitable zone, planet or moon-sized celestial bodies may have liquid surface water and therefore support life, as was the case with Yasiyykk.
