We've learned about space exploration of Mercury, Venus, Mars, Jupiter and Saturn.
Next up is Uranus.
It is so far away that only one spacecraft has ever come close to it: Voyager 2.
On September 5, 1977 the Voyager spacecraft was launched into space.
Voyager 2 took 2 years to get to Jupiter, 4 years to get to Saturn, and then 9 years to get to Uranus!
When Voyager 2 made it to Uranus, it found 10 moons that we didn't know existed, studied the air and space around it, found two new rings around the planet, and took pictures of the moons and Uranus.
