Pluto is more than five light-hours away. Thanks to special

the universe in an arbitrarily short subjective time. Whether
you'd be three-dimensional after the ride is another question.

39 astronomical units, not 39 light-hours. The astronomical unit
is the mean distance between Earth and Sun, about 498 light-seconds.
