Default Scientists Identify Tight Window to Visit Uranus

True for both of the pronunciations. Your-anus and Urine-us.

Neptune may
have lucked out in the name game, but its enormous distance from Earth also makes
it an inconvenient destination for space probes.

As a result, Uranus and Neptune are the least explored planets in the solar
system, having only ever been visited briefly by NASA’s Voyager 2 flyby in the
1980s.


Same with Pluto. They are -very- far from Earth.

Even with the large gravity assists at Jupiter and Saturn, it took 9 years to
get to Uranus and 12 years to get to Neptune.

1977 launch, 1986 at Uranus, 1989 at Neptune.
