Spacecraft
Voyager 2
The only spacecraft to have visited all four giant planets, using an alignment that comes round once in 175 years: Jupiter, Saturn, Uranus in 1986 and Neptune in 1989 - the only close look anybody has ever had at the last two. It crossed into interstellar space in 2018, on a course far south of the plane of the planets.

- 1977-08-20 - still working
Path
Open as well, and steeper. Neptune bent it south in 1989, so it leaves the Solar System about 48° below the plane of the planets at some 15 km/s.
Along the way
- Closest to Jupiter
- Closest to Saturn
- The only close look anyone has had at Uranus
- The only close look anyone has had at Neptune
- Crossed the heliopause, six years after its twin
