Indeed, one of the few things we do know is that much of our knowledge about their appearance is no longer accurate, because they are not static. That makes it hard for even the best telescopes to pick out their features. They are also small and far away, covering just 3.8 and 2.3 arc-seconds of the EarthвЂ™s sky, respectively. Apart from the Voyager 2 spacecraft, which flew past them in the 1980s, no human-built probe has ever ventured near them. Uranus and Neptune are the least-explored planets in our solar system.
