The most brilliant object visible dur
ing the first part OF the nights Oh seq
TENDER and October is the planet Jupi-
ter, situated in the constellation aqua
RUS, rising little before sunset anu
setting little before sunrise. AT pres
emit jupiter is a most beautiful OBJECT 70
one pOssessed of telescope, even VI
only ordinary power. The JoVian SIS
tiers. composed OF six members, lncluu-
ing jupiter, are most interesting com
bination OF primary and secondary pla1
cts. and more than secondary, for mas IL
not but lately been discovered l Ina'
Calisto, the outermost sateiiite
of Jupiter, is accompanied Ia
her orbit around its primary oy litIie
moon discovered at the LICK OBSERVE
tory of California)? The whole sys-
tenn, except the little one just mehtion
ed, may be seen with an ordinary par Vi
field or marine glasses, and on clear
night two of the largest sateilltes arc
easily seen with a pair OF good opera
Qlasses-the rapid movements OF the
satellites around Jupiter afford the en-
thusiastic observer an eVer-varylng con-,
bination. OCCUPATIONS, eclipses anu
transits are Of daily occurrence, ana aI
rare intervals two and even three OF tne
satellites are out of view. ProDaOly Ihe
most interesting event Is q transit ol
the cone OF shadow that projects out ID
opposition TO the sun; while the satel-
lite itself disappears on the race VI ou-
piter, the cone of shadow may DC oo,
served as it journeys across the race VI
the great ball OF light.
There is not great deal known OF the
physical condition Of Jupiter an account
of its enormous distance from the earth,
but the elements OF it's satellites are so
nicely cumpted, and their motions so
so steady as to put to shame the mosV
finely regulated chronOmeterS ana sloer-
ial clocks, and the mariner out on the
ocean may put his utmost confidence in
the fact that while his clock may De
on time. Jupiter is considerably larger
than all of the other members OF the
solar system (the sun excepted anu
may be readily distinguished from all
other celestial objects by it's steady, pc
cular splendor and magnitude. 10 th2
naked eye 1t is as large and distinct as
the planet Venus, although situated In
space nearly eleven times farther than
the latter. Jupiter moves through his
orbit at mean rate OF ABOUT
10000 miles per hour and can be traced
from one constellation in the zodiac to
the next preceding In one years ooser-
walton, and in little short OF l. years
can be followed in one complete circuit
OF the zodiac. Jupiter, when viewed
through a good telescope, appears TO be
grit about with a series OF dark belts,
sometimes shifting and changing In
form and broken, but at all times visible
as zones of dark and light streaks, eX-
tending clear across the face or the
planet. The cause of these belts is not
known, but it is supposed to be atmos-
pheric, and that the shifting and I'M
stable conditions are the result OF ter
iic storms In the elements cOmpris-
ing the atmosphere Of Jupiter. The
mean distance Of Jupiter from the sun
is 395, 600, 600 miles. As situated at
present he Is that distance from the
earth, less the distance Of the earth
from the sun, while at conjunction the
entire orbit Of the earth must be added
to this mean distance from. the SUI to
get at his distance from the earth.
Jupiter revolves on his axis in little
less than 10 hours, giving the residents
Of Jupiter, If he has any, a night OF
nearly five hours and day OF equal
length. Through a telescope the planet
does not have the appearance OF per-
feet globe, but IS very much flattened at
the poles, the effect Of his very rapid
revolutions on his axis which has
tendency to bulge out the equator at
the expense of the polar diameter. The
planet IS nearly 5000 miles larger
in diameter through the equator than
in line extending through
the poles. The equatorial diameter OF
Jupiter is s6,225 miles, which is nearly
eleven times the diameter Of the earth.
Unlike the earth his poles are perpen-
dicular to the plane of his orbit; there
fore Jupiter's residents enjoy one con-
tinuous and apparently unchanged sea-
son. At the equator the sun will rise
directly in the east and set directly OPP
poSite in the west, and all situations,
either north or south, will be subject TO
precisely the same conditions of eli
mate, while at the poles rigid cold must
prevail forever without change, as the
sun can never get above the horizon Of
those places.
Anyone who has an opportunity to
look at Jupiter through good telescope
and neglects his chance misses one Of
the grandest sights that can be viewed
