Voyager 2's closest approach to Jupiter was on July 9, 1979. The voyager's took more than 33,000 photos and it's five major satellites. Though they have been studying Jupiter from telescopes for years, researchers were amazed at the Voyagers' findings. They had a new grasp on crucial physical, geological, and atmospheric processes in the planet, its satellites, and magnetosphere.

In August of 1981, nine months after Voyager 1, Voyager 2 encountered Saturn. Voyager 2 images were taken with green, violet, and ultra violet filters were combined to produce this image. Voyager two was behind Saturn, and it measured the temperature and density of Saturn's atmosphere with penetration of a radio beam.

In January of 1986, Voyager 2 flew closely past Uranus. The spacecraft came within 81,500 km of the planet's cloud-tops. Voyager 2 radioed in many types of data about the planet's moons, rings, atmosphere, interior, and the surrounding magnetic environment. The spacecraft discovered 10 never-before-seen moons of the planet. It also determined that the temperature of the distant planet receives very little sunlight year round, so the temperature at the equatorial region is the same as that of the poles.

In the summer of 1989, Voyager 2 was the first spacecraft to have observed Neptune, it's final planetary destination. This was Voyager 2's closest planetary approach since it was launched; it was 3,000 miles above Neptune's North pole. Then, five hours later, Voyager 2 was 25,000 miles away from Triton, Neptune's biggest moon. This was the last solid the spacecraft would be able to study.
