= Answer = None The following spacecraft have passed the last known body, ie Pluto Pioneer 10 and 11 Voyager 1 and 2 New Horizons will leave the solar system after flying past Pluto in July 2015. The solar system does not really end with Pluto. Besides the planets, there is a thin haze of dust (some of it bunched into comets). Any of this dust that is nearer to the Sun than to any other star may be in the gravitational hold of the Sun and so counts as part of the solar system. Voyager 1 is now near the Sun's heliopause [See Link]. The heliopause is the theoretical boundary where the Sun's solar wind is no longer great enough to push back the stellar winds of the surrounding stars. = Answer = It is true that none of the 5 spacecraft have to date left the physical environment of the solar system, however all 5 of them have sufficient kinetic energy to escape the Sun's gravity. Their escape from the solar system is therefore guaranteed, nothing that man or nature can do, short of an asteroid impact, can stop them from leaving the solar system. By having acquired sufficient velocity to exceed solar escape velocity, they can be said to have left the solar system. Even New Horizons, which will not complete its Pluto reconnaissance mission until 2014, has already escaped from the solar system.
Nothing man-made has left our solar system yet. The furthest thing is Voyager 1, which is now about 116AU away from Earth, around 10.8 billion miles - at the edge of our solar system.
It's Pioneer 10, launched in March 1972. Pioneer 10 first explored the asteroid belt, then moved on to Jupiter. After that, it explored other outer planets and eventually went outside of the solar system, thus becoming the first spacecraft to flay past Pluto.
The gravitational pull between earth and the spacecraft will become insignificant.
There are a few steps of a solar system project. You first have to study the solar system.
NASA named a spacecraft after Galileo to honor his contributions to astronomy and science. Galileo was a pioneering astronomer who made significant discoveries such as the moons of Jupiter, which paved the way for our understanding of the solar system. Naming a spacecraft after him symbolizes NASA's commitment to exploration and discovery.

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.
because they are far away from our solar system
Yes, Pioneer 10 left the solar system. It was launched in 1972 and became the first spacecraft to travel through the asteroid belt, sending back valuable data as it journeyed towards the outer regions of the solar system. Contact with Pioneer 10 was last made in 2003, when it was over 7.6 billion miles away.
Pioneer 10 was the first spacecraft to venture to the edge of the solar system. Hope I could help! :) :)

Depends "very" much on the definition of the boundary of the solar system, but it's possible Voyager I may well have.
Yes. It is never going to leave the solar system.
The gravitational pull between earth and the spacecraft will become insignificant.
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 1.
