The Voyager 2 spacecraft is an unmanned interplanetary space probe launched on August 20, 1977. Both the Voyager 2 and the Voyager 1 space probes were designed, developed, and built at the Jet Propulsion Laboratory near Pasadena, California. Identical in form and instruments with it's sister Voyager 1, Voyager 2 was launched on a slower, more curved trajectory.
Voyager 2 did become the first and only spacecraft to make the spaceflight by Uranus and Neptune, and hence completing the Planetary Grand Tour. This is one that is made practical by a seldomly-occuring geometric alignment of the outer planets (happening once every 176 years).
The closest approach to Jupiter occurred on July 9, 1979. It came within 570,000 km (350,000 miles) of the planet's cloud tops. It discovered a few rings around Jupiter, as well as volcanic activity on the moon Io.
The closest approach to Saturn occurred on August 25, 1981.
The closest approach to Uranus occurred on January 24, 1986, when Voyager 2 came within 81,500 kilometers (50,600 miles) of the planet's cloud tops. Voyager 2 also discovered 10 previously unknown moons of Uranus.
Voyager 2's closest approach to Neptune occurred on August 25, 1989.
With the decision of the International Astronomical Union to reclassify Pluto as a "dwarf planet" in 2006, the flyby of Neptune by Voyager 2 in 1989 became the point when every large planet in the Solar System had been visited at least once by a space probe.
On August 30, 2007, Voyager 2 passed the termination shock into the heliosheath, approximately 1 billion miles (1.6 billion km) closer to the Sun than Voyager 1 did.
As of June 26, 2009, Voyager 2 was at a distance of around 13.375 billion km from the Sun.
Voyager 2 is expected to keep transmitting weak radio messages until at least 2025, over 48 years since it was launched.
Each Voyager space probe carries a gold-plated audio-visual disc in the event that either spacecraft is ever found by intelligent life-forms from other planetary systems. The discs carry photos of the Earth and its lifeforms, a range of scientific information, spoken greetings from the people and childrens of the Planet Earth and a medley, "Sounds of Earth", that includes the sounds of whales, a baby crying, waves breaking on a shore, and a variety of music.

@TheArmstrong1969 la sonda un giorno verrà captata da qualche altra forma di vita chissà magari da altri esseri umani.
