On 24 January 1986, Voyager 2 made its closest approach to Uranus. The probe came within 81,500 km of the cloud tops of the planet.
Voyager 2 measured the spin of the planet to be 17 hours 14 minutes and discovered a complex magnetic field as well as the new small moons. Voyager 2 is so far the only manmade object to reach Uranus and, as yet, there are no concrete plans to return.
