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.
