1892. Astronomers claim that there
are u 500, 900 comets in the solar sys-
tenn.
An error of thousandth part of q
second in an astronomical calculation
would mean an error of zoe, 900, 900,
600 miles In the distance of a star.
The calculations of the astronomer
Baily proved that the weight of the
ear tn Is 6,049, 1886, 900, 900, 900 tons.
The motion of the earth around the
sun is 68.SH5 miles an hour; over 1000
miles minute, or nineteen miles q
second.
There are twenty stars of the first
magnitude and seventy of the second.
The spectroscope has demon strated
that all the sO.called fixed stars are
in motion-some in one direction,
some in another.
The spectroscope has showed that
the promInences on the sun are out
bursts of glowing hydrogen.
Some of the stars move with the
velocity of nearly fifty miles a second.
The moon is without water and des-
titute of al atmosphere.
The strongest telescopes bring the
moon to an apparent distance of 100
miles.
The tail of comet is believed to be
matter similar to that contained in
the nebul2.
The earth has three motions: round
its axis, round the sun, and with the
