JUPITER PLANET
WITH nine MOONS
MOST BRILLIANT STAR OF THE
SKIES HAS MANY
SATELLITES
Wanderers Of the Celestial Family
Appear to Advantage Now

Jupiter Is by far the most interest
ing thing to study in the skies now.
Even an opera glass or small teles-
cope will bring to light one or two OF
his moons. For long time he was
credited with having only four satel-
lltes, but he is now known to have at
least nine-the latest one having been
discovered only last year.
In fact Jupiter and his family Of lit
tie moons presents almost model OF
our solar system-Jupiter himself rep
resenting the sun, and his moons rep.
resenting the planets. The largest sat
elite Is calculated to be about 3,70O
miles in diameter, or say little over
half as big as our moon.
Think of living on planet where,
instead Of having only one moon as
we do, which gives good light only a
fraction OF the time, there would be at
least nine moons, of varying sizes and
distances, all coursing around the sky
OF different speeds. 1t must puzzle the
astronomers on Jupiter. If there are
any there, to keep track Of the move
ments Of all these moons. And we
must remember that there may be
other moons which our telescopes
have not yet picked up.
While the clock hour hand makes
two revolutions in the twenty-four
hours, the sky makes one. By remem-
bering this fact and familiarizing
yourself with the stars you can tell
time roughly by looking at the heav-
ems at night.
OF course when We speak of the
sky revolving" we mean only that IT
reyolyes in relation to the earth; as
everyone knows, it is really the earth
that is rotating, but It is simpler to
think of the sky as turning. The pivot
| al point of the skies Is the north star,
whose position above the northern
horizon is just euqal to the latitude
of your location.
The planets are not shown on star
maps, for the reason that their posi-
ton is constantly changing. At pres
ent the planet Jupiter is the most brill
liant object in the heavens, after the
sun and moon, but it will not be found
on the map.
East of Andromeda Is the little tri
angle of stars in Aries. Further east,
nearer the horizon. the very brilliant
| groups which characterize the winter
| skies are just coming on the scene;
they will be seen to much better ad
vantage later in the year. A little fur
ther round to the northeast Is the con
stallation Auriga, with its brilliant
yellow star Capella. Between Auriga
and the zenith Is the constellation
perseus. containing the wonderful
variable star Algol, which is much
brighter at some periods than at 9th
ers.
