Sanghelios

Sanghelios is the homeworld of the Sangheili race. Sanghelios is the fourth planet in a triple star system containing Urs, Fied, and Joori. The planet has two moons called Qikost and Suban. Many Forerunner artifacts and structures exist on the planet, which are the topic of worship, as well as the cause of historical wars between the Sangheili and the San 'Shyuum before the formation of the Covenant.

Background
Sanghelios has a gravity of 1.375 Gs, and an average surface temperature of -5°C to 96°C (23°F to 204.8°F). Sanghelios is inhabited by approximately 8.132 billion Sangheili. The Bestiarum indicates that Sanghelios is similar to Earth in shape and proportion, though the land masses are more scattered in relation to bodies of water. Like Earth, its atmosphere consists of oxygen; carbon dioxide and nitrogen, but also has a reddish hue to it, perhaps indicating large amounts of haemotite or molten rock.

Being a homeworld, the planet is home to a huge number of civilian Sangheili numbering over eight billion, as well as a large defense force. Sanghelios was possibly an area of heavy conflict between Separatist and Loyalist forces.

It is also possible that the Sangheili population centers on the planet are all city-states, as the State of Vadam is seen in The Cole Protocol.

Trivia

 * The name "Sanghelios" comes from the Latin sanguis and the Greek helios meaning "Blood-Sun". It is implied that this may refer to the emphasis on "blood" in the culture of the warrior Sangheili that live there.
 * In the Doctor Who episode "Planet of the Dead", the planet they are teleported to is called San Helios, which is also part of a triple star system.
 * In Halo: The Cole Protocol, Sanghelios is once mistakenly referred to as "Sanghelion".
