When did people think Uranus was a star?
People may have seen Uranus as early as 128 B.C. but, each time they saw it, they said it was a star. In fact, the man who we credit with discovering the planet got it wrong too! Sure, he knew it wasn’t a star, but he didn’t think it was a planet either.

Are there any other spacecraft that have visited Uranus?
Only one spacecraft has visited distant Uranus. After traveling more than 1.8 billion miles (3 billion kilometers) in nine years, NASA’s Voyager 2 gathered much of its critical information about the mysterious planet, including its rings and moons, in just six hours.
