the huge isolation of the solar system.
The sun with its specks of planets,
its dust of planetoids,
and its impalpable comets,
swims in a vacant immensity
that almost defeats the imagination.
Beyond the orbit of Neptune there is space,
vacant so far
as human observation has penetrated,
without warmth or light or sound,
for twenty million times a million miles.
That is the smallest estimate of the distance
to be traversed
before the very nearest of the stars is attained."
(H.G.Wells - The Star)
