The Uranian moon Miranda, imaged by Voyager 2. Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years. The length of a day on Uranus as measured by Voyager 2 is 17 hours and 14 minutes. Uranus is ...
Voyager 2 was also to explore Jupiter and Saturn, but on a trajectory that would have the option of continuing on to Uranus and Neptune, or being redirected to Titan as a backup for Voyager 1. Upon successful completion of Voyager 1 's objectives, Voyager 2 would get a mission extension to send the probe on towards Uranus and Neptune. [ 13 ]
Voyager 2 was the first to be launched. Its trajectory was designed to allow flybys of Jupiter, Saturn, Uranus, and Neptune. Voyager 1 was launched after Voyager 2, but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan, [21] which
An image of the planet Uranus taken by the NASA spacecraft Voyager 2 in 1986. New research using data from the mission shows a solar wind event took place during the flyby, leading to a mystery ...
This odd discovery led the Voyager scientists to conclude that the moons must be entirely inactive. But a new analysis of the Voyager 2 data showed that Uranus experienced a rare cosmic occurrence ...

This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: It includes: All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes .
