User:XW3 AR3 L3GION/Urs System

The Urs System is a triple star system on the outer edges of the Orion Spur and is the home system and captial of the Sangheili and Sovereign Territories, respectively.

Stellar Composition
The Urs System is a triple star system with Urs being the primary K-type star with two orbiting white dwarfs, Fied and Joori. It is theorized that Fied and Joori were actually rouge stars pulled from their original systems by some form stellar phenomenon before being captured by Urs' massive gravity well and that the addition of the two new stars caused the 'zone of habitation' to be forced back to the fourth planet, otherwise life might have developed on the third planet instead similar to Earth.

Lor
Lor is a small terristrial planet with an thin atmosphere comprised of nitrogen monoxide and ammonia. Being the closest planet to the three stars, it has a surface temperature of 139-23 degrees through its 490 year long day-night cycle. However despite being unhabitable the Sangheili have mantained a automated solar station on the polar extremes since before joining the Covenant, which powers the

Thanum
Thanum is a Venusian hothouse known for its ancient Sangheili training grounds where young Sangheili would prove their worth by fighting in full enviromental body armour at temperatures of 90 degrees.

.

Mata
Mata is terrestrial with a dense atmosphere of carbon monoxide and argon with huge deposits of Tritanium. These deposits were first discovered by the United Sangheili States - the Sangheili government before joining the Covenant Empire - in the construction of their warships. The world is still littered with automated mining stations still churning out millions of tonnes of raw unprocessed Tritanium ore.

Sanghelios
Sangheilos is the homeworld of the Sangheili race. By 2580, it was home to over ten billion Sangheili natives and was one of the most heavily defended planets known at the time as it faced several raids from Covenant Remnant factions.

.

Epta
Epta is hydrogen-helium gas giant known for its hydrogen mining and refining plants that hangs from an orbital space station. The plants produces liquid deuterium which is used as fuel on Sangheili ships. Due to multiple deuterium stations in the Covenant Empire, the few on Epta were neglected although not shut down and have been hoarding billions of gallons of deuterium since.
