ASTRONOMY.

1910. Inc fers teieocope Uullr' 4Js
inch aperture; Observatory OF Paris.
1877. Hall. OF Washington, disoov.
ered two satellites Of Mars.
1877. Oxygen discovered In the solar
system by Draper, OF New York
1878. Watson claimed to have seen
Vulcan during solar eclipse.
1881. No loss than seven distinct
comets were visible during this year.
1881. Draper's remarkable discoveries
In photographing nebula and comets.
1882. Transit OF Venus observed by
parties sent to Now Zealand, Australia
and elsewhere.
1882. The Lick telescope begun; the
largest yet made.
1892. Astronomers claim that there
are IL, 500, 900 comets in the solar sys-
tenn.
1892. Il Is claimed that over Elk hun
dred comets have been seen and re-
corded.
THE moon is without water and des-
titutc OF an atmosphere.
THE nearest fixed star Is p, ,OOO, ,OOO,-
600 miles from the earth.
SOME Of the stars move with q vc-
locity Of nearly fifty miles seond.
THE fixed stars are suns, and each
may have its own planetary system.
The fixed star second in distance Is
SO, ,000, 600, 600 miles from the earth.
THERE are twenty stars OF the first
magnitude and seventy Of the second.
THE fixed stars are Of oil colors, vio-
let, blue, green, and red predominat-
ing.
To THE naked eye 1900 stars arc
visible; the best telescopes show $780,
OoO.
THE strongest telescopes bring the
moon TO an apparent distance OF 100
miles.
THERE are stars whose diameter 10
greater than that of our whole solar
system.
THE tail Of q comet Is believed to be
matter similar 70 that contained in the
nebulB.
THE planets Venus and Mars most
nearly resemble the earth in climatic
conditions.
THE suns volume is 1,4o7,l24 times
that OF the earth, and coo times greater
than all the planets.
THE earth has three motions: round
its axis, round the sun, and with the
sun and solar system.
THE spectroscope has showed that
the prominences on the sun are out
bursts OF glowing hydrogen.
THE moon gives out heat enough to
affect thermometer and make differ
ence OF two or three degrees.
THE calculations of the astronomer
Baily proved that the weight Of the
earth is 6,049, 1886, ,O00, ,0O0,0 tons.
SOME stars are believed to be so far
away that 1000, 900 years are required
for their light to reach the earth.
SUN spots 100000 miles in diameter
have been measured, large enough to
hold dozens of such worlds as ours.
SOME stars are so distant that, trav-
cling 200, 900 miles a second, their light
requires $4,000 years to reach the
earth.
THE motion of the earth around the
sun Is sc, ,305 miles an hour; over 200
miles minute, or nineteen miles
second.
THE spectroscope has demonstrated
that all the so-called fixed stars are In
motion-some in one direction, some in
another.
AN error OF thousandth part OF
second In an astronomical calculation
would mean an error OF 200, ,000, ,000, 900
miles In the distance of star.
THE solar system is well illustrated
by the following statements: Lot the
sun be represented by globe two feet
In diameter. A grain OF mustard seed
ut the circumference Of q circle 164
feet in diameter will adequately repre-
sent the size and distance OF Mercury.
The earth will be represented by pea
ON the circumference of circle 284
feet across, and Venus by another pea,
on the outside Of 430-foot circle. Mara
will be adequately represented by
pin-head at 654 feet, and the Asteroids
by grains of sand 1000 to 1000 feet
away. An orange at the distance OF
half mile will stand for Jupiter,
very small apple at four-ffths OF mile
will answer for Saturn, and a cherry on
the circumference Of circle q mile
and half across will represent Uranus.
