Quick-forward to 1977, and NASA launched the primary of two spacecraft designed to conduct the primary tour of the photo voltaic system.
Voyager 2 flew closest to Uranus in January 1986. The flyby at 50,600 miles above the cloud tops of Uranus provided the primary detailed take a look at the planet, its moons, rings and environment. Quickly after, astronomers have been making discoveries about Uranus because of Voyager 2’s flyby.

Later, the Hubble Area Telescope and ground-based telescopes introduced the Uranian moon whole to 27.
Uranus is taken into account an ice big as a result of most of its mass is ice made up of water, methane and ammonia, in accordance with NASA. A Uranian day takes about 17 hours and about 84 Earth years to finish one solar orbit.
Voyager 1 and a couple of spacecraft continued on and are nonetheless speaking with Earth through the Deep Area Community. In 2012, Voyager 1 grew to become the primary human-made object to enter interstellar area.
Voyager 2 was the final customer to Uranus. No different spacecraft has accomplished an in depth flyby since.
