It is a matter for regret that Uranus does not come more easily within
our view; for he is a very beautiful planet, pale green in color, and
unlike any of the others in his aspect. There are, however, very few
persons nowadays who can see him without the aid of at least a small
glass, and to most of us he must ever remain a body with which we can
have no personal acquaintance. None the less he must have an interest
to us such as attaches always to anything so closely related to us,
and sharing with us a common origin and a common destiny. To those who
have unusually keen vision--or a small telescope--there will be much
pleasure in viewing the planet. But even to those who have not these
facilities for seeing, it ought to be interesting to know in what
region of the skies this far-off member of our family dwells, what his
wanderings are, and something of his personality and habits.
It requires a few days more than eighty-four years for Uranus to make
one revolution around the sun, so that he moves even more slowly than
Saturn from one constellation to another; and if we could only see him
more easily, he would be scarcely more difficult to keep track of than
a fixed star. He remains in each constellation somewhere near seven
years and his change of place in the skies amounts in one year to but
little more than four degrees, which is less than the distance between
the pointers.
Since Uranus was discovered he has made one circuit of the skies, which
he finished in 1865, and he is now (1912) more than half-way around
on another. His position now is in Capricornus, nearly twenty degrees
east of the “milk dipper” in Sagittarius, and for the next quarter of a
century he can be seen by any who have eyes, or a glass, to accomplish
this during the summer evenings. Each year he will be about seven
degrees farther east. He is, however, still pretty far south of the
equator, and not so easily seen as he will be when he reaches that
part of the ecliptic which runs somewhat higher in the skies. Even an
opera-glass will bring Uranus into the view of many persons. His path
deviates very little from the line of the ecliptic--never quite so much
as half a degree. The knowledge of this makes it less difficult to find
him.
The synodic period of Uranus is about three hundred and sixty-nine
days, so that an opposition occurs about four or five days later each
year. He was in opposition this year (1912) on July 24th. In 1913 an
opposition will take place on July 29th, and in 1914 on August 2d, and
oppositions will occur about four days later each year thereafter.
