Whirling over at this rate would cause the sun to appear to skim across
the sky very swiftly as viewed from Saturn. In size, it would not seem
more than three times as large as Venus at her brightest seems to us,
and every minute it would cover a distance about equal to the diameter
of the full moon as we see it. In an hour it would seem to move more
than six times as far as the distance between the “pointers.” At the
time of Saturn’s equinox the little five-hour day, followed by the
equally short night, must present a lively aspect with the sun racing
thus swiftly across the sky in daylight and the stars sweeping as
swiftly over at night. If things remain as they now are, it will be a
splendid panorama for the people there when, in the far-distant future,
Saturn may have cooled and solidified sufficiently to maintain life
somewhat as we know it. The earth, though, and Venus and Mars would be
from Saturn only telescopic objects to eyes like ours, and Jupiter no
brighter than he is to us. Thus does our brother Saturn pay the price
of his remoteness from the rest of the solar family.
THE RINGS AND MOONS OF SATURN
But the circling stars and the swift-moving sun are the least part of
the splendid spectacle that might be seen from Saturn. He is surrounded
with no less than ten moons of more or less imposing size, and in
addition has three rings circling around with him, composed of myriads
of small satellites, together forming a band the outer diameter of
which is something more than twenty-one times broader than the diameter
of the earth. These are the famous rings of Saturn, the only objects
of their kind in the solar system, intensely interesting to scientific
observers, wonderful to the curious, and splendidly beautiful to
everybody. It is this profusion of rings and moons that entitles Saturn
to be called, as he often has been, the most spectacular of all the
planets.
The outer ring is nearly ten thousand miles broad, and is separated
from the next one by a space of about seventeen hundred miles. The
second ring is nearly eighteen thousand miles across. It is very bright
on the outer edge, but gradually grows less so, until, with a not
very perceptible division, it fades into the inner ring, which is but
slightly luminous, and is called the crape ring. This is about nine
thousand miles broad and nearly ten thousand miles from Saturn. This
gradual fading of the rings to a dusky hue toward the center, and then
the blackness of the space between them and the planet, gives them from
certain points of view a nest-like appearance; and my first impression
of Saturn, when I saw him through the telescope, was that he was
nestling in a concave body of light--an appearance that is intensified
by his extreme flatness at the poles.
