Voyager 2 reaches Uranus — the only close encounter ever made

node

Because Uranus is tipped almost onto its side, its moons and rings lie in a plane nearly perpendicular to an approaching spacecraft, so the entire system had to be observed in a few hours rather than over days. Voyager 2 found around ten new moons, further rings, and a magnetic field steeply tilted from the rotation axis and offset from the planet's centre. Forty years later this remains the only close observation of the planet in existence.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.

  38. Evidence
  39. The encounter dates and principal findings at Jupiter, Saturn, Uranus and Neptune, including the Jovian ring, the resolved ring structure at Saturn, the tilted and offset Uranian magnetic field and the newly found moons at both ice giants. V55 verification basis: THE PAGES WERE NOT REACHED — science.nasa.gov is blocked by this session's egress proxy and the search budget was exhausted. Everything attributed here is standard mission record from general knowledge; a curator must confirm each encounter date and each count of newly discovered moons against NASA's own pages.
