That kind of depends on where you consider the boundary of "the solar system" to be.
It's currently in the "heliosheath" and will probably reach the heliopause... which is one reasonable definition of "outside the solar system"... within the next ten years or so. Voyager 1, which is further away and moving faster, is expected to reach this boundary in about 2015, but Voyager 2 reached the heliosheath significantly closer to the Sun than Voyager 1 did... this boundary appears to be "dented" in the direction that Voyager 2 is heading.
Voyager 2 is well outside what most non-scientists think of as "the solar system" already... it's over twice as far from the Sun as Pluto is, for example.
Voyager 1 and Voyager 2 have both left the heliosphere, but neither has left the solar system. The edge of the solar system is considered to be the outer boundary of the Oort Cloud, The exact width of the Oort Cloud is not known, but its estimated that it would take Voyager 2 about 300 years to reach the inner boundary of it. To reach the outer boundary of the Oort Cloud, truly leaving the solar system, would take Voyager 2 something like 30,000 years.
It is just leaving the solar system. We know this because the data it is sending back shows that the density if the solar wind is dropping dramatically.
The Voyager program was designed to study Jupiter and Saturn but was extended to study Uranus, Neptune, and the outer reaches of the solar system. The planetary alignment that allowed Voyager 2 to visit four planets was an opportunity that would not recur for 175 years.
Voyager 1 is on the edge of inter-stellar space, Voyager 2 is a little closer. "As of August 2010, Voyager 1 was at a distance of 17.1 Billion Kilometers (114.3 AU) from the sun and Voyager 2 at a distance of 13.9 Billion kilometers (92.9 AU). Voyager 1 is escaping the solar system at a speed of about 3.6 AU per year, 35 degrees out of the ecliptic plane to the north, in the general direction of the Solar Apex (the direction of the Sun's motion relative to nearby stars). Voyager 2 is also escaping the solar system at a speed of about 3.3 AU per year, 48 degrees out of the ecliptic plane to the south." NASA
These are spacecraft, see the related links.The Voyager 1 spacecraft is a 722-kilogram (1,592 lb) robotic space probe of the outer Solar System and beyond, launched September 5, 1977. It still receives commands from, and transmits information to Earth, currently pursuing its extended mission to locate and study the boundaries of the solar System, including the Kuiper belt and beyond.The Voyager 2 spacecraft is an unmanned interplanetary space probe launched on August 20, 1977. Voyager 2 was launched on a slower, more curved trajectory that allowed it to be kept in the plane of the Ecliptic (the plane of the Solar System) so that it could be sent on to Uranus and Neptune by means of utilizing gravity assists during its fly-by of Saturn in 1981 and of Uranus in 1986.
Because they were the first vehicles to leave the solar system.
There has never been a man made object to leave the Solar System. There are however, two objects which may escape the influence of Sol and enter the interstellar medium. These objects are the Voyager 1 and Voyager 2 spacecraft. It is currently unknown which will leave the system first, as although Voyager 1 was launched first, peculiarities of the nature of the Solar System may mean that Voyager 2 breaks the heliosphere first.
Both Voyager 1 and Voyager 2 are on trajectories that will one day cause them to exit the solar system, but they are both still within its accepted boundaries.
Both Voyager 1 and 2 have travelled through the solar system, I believe Voyager 1 is the only one which has left the solar system (or is in the process of).
Voyager 1 and Voyager 2 have both left the heliosphere, but neither has left the solar system. The edge of the solar system is considered to be the outer boundary of the Oort Cloud, The exact width of the Oort Cloud is not known, but its estimated that it would take Voyager 2 about 300 years to reach the inner boundary of it.

Voyager 2 and Voyager 10 There isn't a Voyager 10. You probably meant Pioneer 10.
Voyager 1 and 2 were launched in 1977, and explored the outer planets during the 70's and 80's. They are still partially operational today, on their way out of our solar system. Voyager 1 is the most distant man made object to date, currently around 116 astronomical units from earth.
About 35 years ago.
Voyager 1 and Voyager 2. There is a matter of some debate as to whether the two Voyager probes have actually left the solar system, an where the "edge" of the solar system actually is. Both are beyond the orbit of Pluto, but have not passed beyond the vaguely-defined Kuiper Belt, and the two probes are just approaching the heliopause, the boundary layer between the solar wind and the broader currents of interstellar space. But it seems likely that however that boundary is defined, the two Voyager probes either were or will be the first man-made objects to pass it.
Yes. Much of what we know about Uranus was learned during a pass by the Voyager 2 spacecraft in 1986 on its way to Neptune and after that, to leave the solar system completely.
Voyager II did not land on Uranus, it has left our solar system.
It is just leaving the solar system. We know this because the data it is sending back shows that the density if the solar wind is dropping dramatically.
