Despite the careful work of engineers, Voyager 2 saw only impenetrable cloud at Uranus.

Uranus's moon Miranda, with its fractured surface, proved more interesting to scientists. The Voyager probes were launched in 1977. If Jupiter were much larger it would be a star in its own right!

Enjoy Astronomer Marek Kukula's eloquent guide to the Sun, the planets and the outer reaches of the Solar System. Scientists studying how the Solar System formed are interested in the Kuiper Belt, a region of icy objects beyond Neptune. It is thought that the Kuiper Belt objects may explain the formation of the outer planets Uranus and Neptune.
