A colour photograph of Uranus, taken by Voyager 2 in 1986 as it headed towards the planet Neptune. The exploration of Uranus has, to date, been solely through telescopes and NASA 's Voyager 2 spacecraft, which made its closest approach to Uranus on January 24, 1986.Voyager 2 discovered 10 moons, studied the planet's cold atmosphere, and examined its ring system, discovering two new rings.he Uranian moon Miranda, imaged by Voyager 2. Uranus is the third-largest 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.
Actually, we have-the only spacecraft to visit Uranus was Voyager 2 in January of 1986. The other Voyager spacecraft did not visit any other planets after its encounter with Saturn, while Voyager 2 continued on to Uranus and Neptune. All of the up close images we have of them are from that one spacecraft.he first of the planets to be discovered was named after the muse of Astronomy (Urania). Uranus is also the name of Saturn's father. Uranus was discovered by William Herschel in 1781, though it had been mistakenly mapped in the past as a star.
