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.
Current Known History
Jupiter was known ever since the 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. Humans first sent a spacecraft in late 1973, known as the Pioneer 10. Other spacecraft soon followed, thus discovering more moons and increase the understanding of the gas giant. Jupiter does have rings, but they are much fainter than those of Saturn's, discovered years later after the first spacecraft visit.
Interplanetary War
Jupiter represented a major battle zone during the Interplanetary War.
Jovian Moons Campaign
- Main article: 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.[1]
Human-Covenant War
During the Human-Covenant War, Jupiter was once again a location of particular importance.[3] Io Station detected Covenant Fleet of 15 ships exiting Slipspace just outside of Jovian space a few moments before the Battle of Earth.
