Kurinnur

 (Kurinnurii: Home), alternatively designated as Thitt AB-V, is the fifth planet of the planetary system orbiting the binary component, Thitt AB, of the ternary star system Thitt. Located in the middle circumference of Liimaara, it is the planet of origin for the kurinnurii.

Characteristics
Kurinnur is a large and heavy planet; measuring 1,81 D&oplus; across in diameter and weighs 9,0 M&oplus;. It generates a gravity pull at circa 2,75 g, and has captured stellar bodies to become as its own moons. More so, it maintains a wide ring. Like most other planets, Kurinnur appears spherical, but is oblate spheroid as a more precise shape. The difference between polar and equator in diameter measures up to an approximation of 257 km.
 * Physical

maintains a distance of 4,07 AU to the barycentre of the binary stars, Thitt A and B. The time to finish an orbit takes 6,326 [Earth] years, taking little less than 2309 days to finish one period.
 * Orbital

Kurinnur rotates quickly, a day on Kurinnur is 9 hours, and 17 minutes. Since the planet is tilted about 30 degrees, together with the long orbital period, seasonal changes are big and have significant impacts on the environment of areas surrounding the polar capes.


 * Geochemistry & Structure

Kurinnur has a big iron-nickel core rich on rare and heavy metals, surrounded by a crust rich in nitrates, sulphides and silicates. Due to the reductive (oxides are robbed off their oxygen and replaced by hydrogen) nature of the atmosphere, and the volcanism accompanied with the explosive nature of the magma released by the volcanoes, the surface is dominated by sulphides and nitrates. Oxides and silicates are naturally occurring, but their abundance is varied by exposure to the reductive atmosphere and is dependent on what the oxygen is bound to.

Another effect of the atmosphere realises existence of transient metals, such as iron and silver, in its purest form in all layers. Making them more available at more shallow levels of the crust. It also fosters formation of more unusual minerals such as moissanite (SiC), and other compounds formed around sources of geothermal energy, volcanoes, such as titanium hydride (TiH2).

Nitrates are violate chemicals, Kurinnur is abundant of them, and they are most present in the molten mix from underneath the surface. The nitrates create magma who is violent and explosive in nature, contributing to the much active volcanism and geothermal tectonics

has a fair atmosphere those composition is dominated by nitrogen, hydrogen, and carbon, and to a lesser degree; sulphur and oxygen. The atmosphere also contains traces of noble gases - namely argon, helium and neon. It is speculated that used to possess a thicker atmosphere dominated by hydrogen billion years earlier, since the atmosphere is thick for its age and composition.
 * Atmospheric

Since the atmosphere contains far more hydrogen than oxygen, it is reductive in nature. Most gases, chemicals and compounds, are merged with hydrogen atoms to produce gases containing hydrogen, some cases rob them off their own oxides to create other gases or chemicals, that can't be reduced again.

The atmosphere is stratified to two significant atmospheres, with a thin layer of hydrogen encapsulating the two atmosphere inside and ultimately defines the border between Kurinnur's atmosphere and the outer space. At sea level, the pressure is estimated to be 44,7 atm - equivalent to nearly 45 times the pressure of Earth.


 * Hydrospheric

Satellites
A 26'515 kilometre wide ring surrounds 's equator. Its appearance divides it into three different rings, two obviously visible to the bare eye, and one less visible ring, defining the outer perimeter of the ring. The rings are composed of small rocks, captured asteroids, comets, and meteorites, that had collided with each other and had left tons of fine dust in its wake. This collection is more dense as the more inwards it goes to the host planet,.
 * Rings

has six moons, whereas four of them are classified as dwarf moons. Only four - the closest dwarf and the three biggest; Othenbur, Phinjaar, Jonemar, and Feanmoor - of the six moons were observed by the ancient civilization of the kurinnurii. The other two dwarf moons, Thinyju and Bernmar, were later discovered when optical instruments were developed and were pointed to the sky.
 * Moons

Sorted by their orbital distance to Kurinnur, the closest satellite is Othenbur, followed by Phinjaar, Jonemar, Feanmoor, Thinyju, and then Bernmar.
