Sanghelios

Sanghelios is the homeworld of the Sangheili race. Sanghelios is the fourth planet in a Triple Star System of stars Urs, Fied, and Joori. The planet has two satellites called Qikost and Suban. Many Forerunner artifacts 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 proper.

Background
Most likely due to the fact that Sanghelios has three suns, the surface is dry and arid, although water exists on the planet. The planet as it is illustrated in the Beastarium indicates that it is similar to Earth, though the landmasses are more scattered in relation to bodies of water. Its atmosphere has a reddish hue to it, like Mars' atmosphere.

Surface temperatures usually range from -5C to 96C. Surface gravity is slightly higher than Earth's at 1.375 G's, and has an Earth-like atmosphere consisting of Oxygen, Nitrogen, Carbon Dioxide, and other gasses. Approximately 8.132 billion Sangheili live on the planet.

Notable places on the planet include one of the most prestigious war colleges in the Iruiru Region of Yermo. The planet is of course home to a large number of civilian Sangheili, as well as a large defense force (possibly a large fleet). Sanghelios may be the site of large conflict between Separatist and Loyalist forces.

At the end of Halo 3, the Arbiter, Rtas 'Vadum, and the crew of the carrier Shadow of Intent depart for Sanghelios.

Etymology
The name "Sanghelios comes from the Latin sang and the Greek helios which mean "Blood-Sun". It is implied that this may refer to the "hot blood" of the warrior race that lives there.
