| '''Jupiter''' is a [[planet|gas giant]] and the fifth planet in the [[Sol system]]. It is the second largest body in the system, behind [[Sol]] itself but ahead of [[Saturn]].{{Ref/Reuse|ENC295}} | | '''Jupiter''' is the largest planet in the [[Solar System]]. It was the site of various battles, dating back from the [[Interplanetary War]] to the [[Human-Covenant War]]. |
| | |
| ==Overview==
| |
| [[Human]] scientists have studied Jupiter's winds to learn about the formation of storms. The gas giant's intense radiation, planetary ring system, and orbital path have also been analyzed by scientists to help them explain other mysteries in the galaxy.{{Ref/Book|Id=ENC295|Enc11|Page=294-295}}

| Jupiter is orbited by a number of [[natural satellite]]s, referred to as the [[Jovian Moons]].{{Ref/Book|Id=mythos46-47|Halo Mythos|Page=46-47}}{{Ref/Reuse|encyc32-33}} At least four—[[Europa]], [[Ganymede]], [[Io]], and [[Callisto]]—have been colonized by humanity.{{Ref/Reuse|mythos50-51}}{{Ref/Reuse|ENC295}} Jupiter is also orbited by the [[Jovian Habitats]] which include [[Juventus]] and [[Bellona]]{{Ref/Book|Id=Enc22pg40|Enc22|Page=40-41}} as well as the shipyards for [[Martian Metals Shipyards]].{{Ref/Book|Id=Enc22Poseidon|Enc22|Page=127}}

| ===Rise of humanity===
| | Jupiter has been known since ancient times, however its four Major moons, also known as Galilean moons, were only discovered in 1610 by Galileo. In 1892, a fifth moon of Jupiter was discovered, but smaller than the four others. [[Human]]s first sent spacecraft was in late 1973, known as the ''Pioneer 10''. Other spacecrafts soon followed, thus discovering more moons and increasing the understanding of the gas giant. Jupiter has rings that are much fainter than those of Saturn's, which were discovered years later after the visit of the first spacecraft. |
| Humans began colonizing Jupiter's moons in [[2080]].{{Ref/Book|Id=encyc32-33|Enc11|Page=32-33}}{{Ref/Novel|[[Halo: Contact Harvest]]|Page=37}} The planet itself was settled by gas mining operations and industrial habitats.{{Ref/Book|Id=mythos50-51|HM|Page=50-51}}{{Ref/Note|In the ''Halo Encyclopedia: The Definitive Guide to the Halo Universe'' when discussing Jupiter directly on pages 294-295, it specifically mentions that humanity does not possess the ability to mine gas giants and thus Jupiter is left alone. ''Mythos'' changes this and is displayed instead.}} Many of the satellite habitats were founded to serve as waystations for resource extraction further out in the solar system.{{Ref/Reuse|Enc22pg40}}

| In [[2160]], the [[Frieden]] secessionist movement attacked the [[UN Colonial Advisors]] stationed on [[Io]]. The attack led to the [[Jovian Moons Campaign]], which was one of the conflicts that culminated in the [[Interplanetary War]].{{Ref/Site|Id=xbox|URL=http://www.xbox.com/en-US/games/h/halo/storyline.htm|Site=Xbox.com|Page=Halo Storyline|D=24|M=04|Y=2008|LocalArchive=Archive:Xbox.com/Halo/Timeline|Detail=(Additional copy on [http://halo.bungie.org/misc/mstimeline2.html HBO Forums])}}

| The planet of [[Concord]] in the [[Alabaster system]] would become of interest to settlement co-ops based in the Jovian holdings.{{Ref/Book|Enc22|Page=44}}
| | ===Interplanetary War=== |
| | Jupiter represented a major battle zone during the [[Interplanetary War]]. |

| | ===Jovian Moons Campaign=== |
| | {{main|Jovian Moons Campaign}} |
| | During the Jovian Moons Campaign of [[2160]], the [[Frieden]] secessionist movement attacked the [[UN Colonial Advisors]] stationed on [[Io]]. The attack led to the Jovian Moons Campaign and the beginning of the [[Interplanetary War]].<ref>http://www.xbox.com/en-US/games/h/halo/storyline.htm</ref> |

| During the [[Human-Covenant War]], Jupiter was once again a location of particular importance.{{Ref/Novel|[[Halo: The Fall of Reach]]|Chapter=??}} On [[2552#October|October 20, 2552]], the [[Prophet of Regret|High Prophet of Regret]]'s [[Fleet of Sacred Consecration]] exited [[slipstream space]] relatively close to Jupiter.{{Ref/Game|Id=terminal8|H2A|Terminal (Halo 2: Anniversary)|Terminal 15}} [[Io Station]] detected the [[Covenant fleet]] of fifteen [[Covenant starship|ships]] and reported the discovery to Fleet Admiral Lord [[Terrence Hood]] a few moments before the [[Battle for Earth]].{{Ref/Level|H2|Cairo Station}} | | During the [[Human-Covenant War]], Jupiter was once again a location of particular importance.<ref>'''[[Halo: The Fall of Reach]]'''</ref> [[Io Station]] detected a [[Covenant Fleet]] of 15 ships exiting [[Slipspace]] just outside of Jovian space a few moments before the [[Battle of Earth]]. |

| Later, around [[2552#November|November 15–16, 2552]],{{Ref/Note|See [[Battle for Earth#Notes|Battle for Earth's Notes section]]}} the [[Forerunner Dreadnought]] and an [[Truth's fleet|escorting fleet]] of the [[High Prophet of Truth]] passed Jupiter while on their way to Earth at the time John-117 commandeered a {{Pattern|Karo'etba|Ghost}} and crashed it into a large number of [[Covenant]] troops.{{Ref/Comic|HU|Issue=1}} Believing the [[SPARTAN-II program|Spartan]] to be dead, the Prophet of Truth orders the crew of the Forerunner Dreadnought to jump further in-system and enter Earth's atmosphere on November 17, 2552.{{Ref/Marketing|Id=LongRoad|Halo Waypoint|The Long Road Home}} Following the [[Covenant]]'s invasion across the Sol system, many habitats of Jovian colonies survived the Covenant assault largely unscathed.{{Ref/Site|URL=https://www.halowaypoint.com/en-us/universe/species/humans|Site=Halo Waypoint|Page=Humans|D=01|M=6|Y=2020}}
