Only 1 probe has flown past Jupiter, Saturn, Uranus, Neptune
NASA's Voyager 2 spacecraft, launched on August 20, 1977, is the only manmade object to fly by all of the outer solar system planets going beyond Neptune in 1989. Further, it is the first spacecraft to image Jupiter, Uranus and Neptune's rings. Travelling at over 56,000 kmph, Voyager 2 is still sending back data from its trajectory towards interstellar space.
