Jouney through the Solar SystemEdit

Since its launch, Voyager 2 has been gone for 36 years. During this time, It has:

  • Studied Jupiter and its four Galilean moons (Ganymede, Callisto, Io amd Europa)
  • Observed Saturn and many of its moons, inlcluding Titan
  • Took the first detailed close-up photos of Uranus and Neptune, along with some of their moons, most notably Neptune's largest moon Triton

Encounter with JupiterEdit

Jupiter Ring
The closest Voyager 2 ever became to Jupiter was on 9 July 1979 when it came within 570,000 kilometers. Whilst exploring the Jovian vicinity, Voyager 2 managed to find faint rings of Jupiter as well as discovering volcanic activities on the closest moon, Io. Two new small Natural satellites of Jupiter, Adrastea and Metis, were also discovered oribiting just outside of the ring. A third new moon, Thebe, was discovered between the orbits of Amalthea and Io.
