Twenty-five years ago today — January 24, 1986 — the Voyager-2 spacecraft made its closest approach to the planet Uranus.

Its flyby carried Voyager-2 to within 50,600 miles (81,500 km) of Uranus. In addition to taking images of the planet’s rings and known moons, Voyager-2 discovered ten previously unseen moons and two previously unknown rings.
