Question

Quizplus · Accepted Answer

Voyager 2 is the only spacecraft to have visited Uranus and Neptune. Pioneer 10 and 11 were both launched towards the outer solar system, but did not flyby either of these gas giants. Voyager 1 flew by Jupiter and Saturn, but not Uranus or Neptune. Cassini was primarily focused on studying Saturn and its moons, and did not visit Uranus or Neptune. Voyager 2 is the only spacecraft to have visited both Uranus and Neptune. Pioneer 10 and Pioneer 11 were aimed toward Jupiter and Saturn, while Voyager 1 only visited Jupiter and Saturn before continuing on a trajectory out of the solar system. Cassini was aimed toward Saturn only.
