'''Threshold''' is a planet in the [[Soell]] star system.<ref name="sybex-halo">"Halo Story Bible: ''Halo''", ''[[Halo: Combat Evolved: Sybex Official Strategies & Secrets]]'', Chapter 5, page 63</ref> It is an immense gas giant, Diameter: 214,604km (133,349 miles), with one satellite, its moon [[Basis]]. Atmosphere is made up of white [[Ammonia]] clouds, amber-colored [[Ammonium Hydrosulfide]] clouds, [[Phosphorus]] compounds, ice crystals and other gases. Threshold is known to have storms in its atmosphere similar to the storms that occur on the planet Jupiter, since there was a large storm present at the [[Battle of the Gas Mine]].

Threshold's, [[Earth]] Survey Catalog number is B1008-AG.<ref name="sybex-halo"/>

[[Image:Threshold.jpg|right|thumb|The planet Threshold]]

Over 100,000 years ago, it was a part of the sizable and extensive [[Forerunner]] empire. They built at least one automated, viable [[Gas Mine]] complex in the upper atmosphere of the planet, likely harvesting the hydrogen gas of the planet. The hydrogen was probably used as transmutation material for construction, though this is not confirmed. Threshold is a [[Neutral]] location.

Several hundred or thousand years later, upon the discovery of the [[Flood]], the [[Forerunner]]s refitted the [[Gas Mine]]s to serve as [[Flood Research Facilities]]. These facilities proved only one thing: more extreme measures were needed to combat the [[Flood]].

The [[Forerunner]]s then chose the planet as a staging point to construct one of their massive fortress worlds, called [[Halo]] and numbered as [[Installation 04]]. [[Installation 04]] was constructed on the Lagrange point between Threshold and [[Basis]]. It was designed to destroy all sentient life in the galaxy, thereby killing the [[Flood]] through starvation.

In [[2552]], the [[Covenant]] were looking for an artifact from [[Sigma Octanus IV]] to uncover this planet as the location of the "Sacred Ring" in order to start the Great Journey. The [[Fleet of Particular Justice]] followed the ''[[UNSC Pillar of Autumn]]'' there and in a series of events, Installation 04 was destroyed.<ref>[[Halo: Combat Evolved]]</ref>

The [[Heretics]] then took refuge on the [[Gas Mine]] (they had formally been on Basis) before the [[Arbiter_(character)|Arbiter]] and his [[Special Ops]] troops dropped it into Threshold's depths. ''[[High Charity]]'' and its fleet briefly visited Threshold as well, until they [[Slipspace|jumped]] to [[Installation 05]].

Threshold is an immense gas giant. Far larger than Jupiter, the largest planet in our solar system. Its moon, [[Basis]], is in fact the size of a huge rock planet. [[Basis]]' diameter is nearly double that of the [[Earth]]. A completely-to-scale accurate planetary comparison sheet authored by [[Stephen Loftus]] is available [http://nikon.bungie.org/misc/sloftus_planetscale/ here].

*The inner core of Threshold is liquid nitrogen, as told by [[343 Guilty Spark]] during the battle with the [[Heretic]] Leader.

*''Threshold'' is described as purple in the book, [[Halo: The Flood]], though throughout Halo: CE and [[Halo 2]], it is only shown as orange.

*Threshold could possibly have a [[Portal]] located on the planet due to the raging storm that forms under the [[Gas Mine]] that resembles the storm over the Ruin/Crater of [[New Mombasa]].

*It is speculated that [[Portal]]s could be used to transport replacement [[Halo]] [[Installations]] from the Ark to the location of the Halo it replaced, but that would not explain why the [[portal]] would already be activated, unless it was automatically activated when building of the replacement [[Halo]] started.
