Esko

The planet
Esko is the eight planet of the Isträ system. It was named by Emeth Jacostia after his brother. It is both the biggest and most far away planet from the sun of the Isträ system. Despite being so far away into space, it wasn't the last one to be discovered by the Ether astronomist : being the biggest planet in the system, it was actually the first Jacostia had spotted behind the black curtain. More precisely, he was the first to consider it as a planet and not a far star as it was once thought.

Size and structure
Being a gas giant, Esko is not a habitable planet. Because of its massive size, no less than six moons orbit around it as well as an ensemble of ten rings. Its core is made of Palladium, Silver and Rock. The gas surrounding it is composed of an inner layer of solid Hydrogen and a second outer layer of Helium, Hydrogen and trace amounts of Methane. It was also noticed that a thin layer of copper dust is running around the gas giant, giving it an orange tint.

Moons and rings
Because of its size, Esko has 6 moons and no less than 10 rings.

The moons :
The moons of Esko were named after various authors and political figures that have made the history of the Ether race. They weren't named by any particular order and the relation between the size of the moons or they color and the name used for it is non-existent. They are here listed from smallest to biggest.


 * Alerov (a famous painter who has the reputation of having created the Ether Relative Realism genre)


 * Alesia (a female politician who was the very first President of the Council to ever be elected)


 * Hostman (author of a very well know novel, Among the stars, an anticipation novel)
 * Foster (famous architect who designed a part of Union City)
 * Will (the nickname of an anonymous writer who is believed to have drastically changed the codes of litterature)
 * Lowmarsh (a famous explorator and author of the wonders of Helkyynd, a novel that still creates controversy even to this very day)

The rings :
Esker has ten rings grouped in five sub-ensembles separated by more or less wide empty spaces. Each of those ensembles are recognizable by different colors, as the inner one is white, the second one is bright yellow, the third one is sand yellow and the fourth one is gray. Those ensembles seem to have been formed by a succession of meteor showers, during which most of the asteroids got catched in the planet's sphere of influence and started orbiting around it, colliding each other to form its ten rings.

Resources and commercial interest
Because of Esker's distance and its lack of interesting metals, the Planet exploration corps has deemed it unnecessary to attempt proper extracting of the interesting minerals of the gas giant.
