Solar system 'NYX (VDH049)' comprises the star 'NYX' and the retinue of celestial objects gravitationally bound to it: 8 planets and their 524 moons, as well as asteroids, meteoroids, planetoids, comets, and interplanetary dust.

The principal component of this star system is the star 'NYX', a yellow dwarf class star that contains about 99.85% of the system's known mass and dominates it gravitationally. NYX is located more than 3451 lightyears from the center of the galaxy.

Pandia, the fourth planet in this system, features organic life forms although the maximum intelligence remains quite low that have developed a civilisation capable of building larger cities and using computers or other high tech equipment. Its average temperature is 283K (10C) and it's atmosphere contains 19% of oxygen. One year on Pandia lasts 1578 days, one day lasts 10 hours. It's diameter is 18818 km, 1.4 times the diameter of the Earth.

This solar system comprises 8 planets

VDH0491 is a large terrestrial planet (8359 km radius) which orbits its star in 220 Earth days, one day on VDH0491 lasts 11 Earth hours. Its average temperature is 979 K (706 C), its atmosphere mainly consists of nitrogen and it has 4 moons.

Still undiscovered by the only inhabited world in this system, Pandia, this planet is still 'unnamed'.

Etoille is a small terrestrial planet (3475 km radius) which orbits its star in 467 Earth days, one day on Etoille lasts 28 Earth hours. Its average temperature is 718 K (445 C), its atmosphere mainly consists of hydrogen, nitrogen, oxygen and it has 2 moons.

Only visible a few cycles a year, the planet named Etoille is almost a legend in Pandia's astrophysics community. Its erratic orbit has puzzled the foremost scientists in this field and currently few theories of its bizarre behavior have been considered ...

Lady is a very large terrestrial planet (11268 km radius) which orbits its star in 859 Earth days, one day on Lady lasts 9 Earth hours. Its average temperature is 478 K (205 C), its atmosphere mainly consists of nitrogen, carbon dioxide and it has 45 moons.

Mistaken in earlier times as one of the moons orbiting planet Pandia, only recently has its status as planet been accepted by Pandia's astronomers. 'The Lady', as it is often referred to, was witnessed to have her own orbiting moons. Moons are highly rev ...

Pandia is a very large terrestrial planet (9409 km radius) which orbits its star in 1578 Earth days, one day on Pandia lasts 10 Earth hours. Its average temperature is 283 K (10 C), its atmosphere mainly consists of nitrogen, oxygen and it has 40 moons.

Short blue-green coniferous trees, stunted pines and firs crowd the edges of the fast flowing rivers of Pandia. As the frigid streams twist and wind about the heavily forested hills, other vegetation, old and rotting, create the rich loamy floor of the ...

Tor is a large gas giant (54825 km radius) which orbits its star in 48447 Earth days, one day on Tor lasts 8 Earth hours. Its average temperature is 1815 K (1542 C), its atmosphere mainly consists of hydrogen, helium and it has 52 moons.

Ungainly in the Pandia sky, this planet can be seen during rest-watch and journey-watch. Its huge mass can block the view of star NYX and most of the orbiting moons for hours at a time. Its presence alone is responsible for early attempts at religious ...

Shyer is a medium gas giant (29452 km radius) which orbits its star in 89004 Earth days, one day on Shyer lasts 8 Earth hours. Its average temperature is 1123 K (850 C), its atmosphere mainly consists of hydrogen, helium and it has 113 moons.

Mostly hidden from view, this planet peeks out at the odd solstice and is known as 'The Shyer'. It is said that those born on the day of The Shyer will be bestowed with unimaginable gifts and rewards.

Muaddeeb is a medium gas giant (20891 km radius) which orbits its star in 163510 Earth days, one day on Muaddeeb lasts 8 Earth hours. Its average temperature is 1265 K (992 C), its atmosphere mainly consists of hydrogen and it has 115 moons.

Rich with a hydrogen atmosphere, Muaddeeb is most famous for its lush and unusual moons that orbit this mysterious gas giant. As a source of energy, the lucrative hydrogen is continually mined by the neighbouring solar system and transferred to the occupi ...

Loner is a large gas giant (59271 km radius) which orbits its star in 319541 Earth days, one day on Loner lasts 8 Earth hours. Its average temperature is 1143 K (870 C), its atmosphere mainly consists of hydrogen, helium and it has 153 moons.

Named after the 'lost ones', Loner is seen as an orbiting planet separate and alone in the cosmos. It travels through the sky dimmer than the other planets and appears moonless, a testament to the singular life of beings apart from a pack. (In reality, t ...
