THESE have been called the gaseous
STARS. the second group of stars Is
less hot and these have been called
the metallic stars, because they ara

cium, MAGNESIUM. copper, iron and
many 0therS. The third groun -
stars is cooler still, and these ara
called carbon stars, because carbon
is found in them.
a theory called the Nebulas Hy.
potnes.s, Claimed that there was
large cloud made up of gaseous mat
ter, which existed in space. This
matter whirled around at such .
great speed that it gradually solidi-
ned and threw off smaller particles
which are now called suns with their
planets and their satellites.
Relation Of Earth to Sun ana Moon
Not only do all the sblanets revolye
around the sun, but certain of these
themselves have other smaller bod
les reolving around them. We call
such small bodies satellites or
moons. The earth has one of these
satellites and Saturn has tep: one
OF which was discovered in 1905. Our
own moon has diameter of about
1000 miles, and weighs about one.
eightieth that of the earth Its aver
age distance from the earth Is about
5000 miles.
1 The sun and the moon have more
influence upon the earth than have
any other bodies. First the sun gives
us energy in heat and light. Ii it
were not for the heat and light
from the sun, life could not exist.
Ii the sun was much nearer. it would
be too hot and if it were much furth-
er it would be too cold for life. 1
Second, the moon having no heat
shines only by the light reflected up
en- it from the sun: and the moon
causes the tide.
Size of the Sun.
If the sun were hollow the earth
and Moon could be placed inside the
sun, and be about the same distance
from each other as they now are
Th diameter of the sun is about
$4,000 miles. We are about SO mil
lion miles from the sun in summer
and about three million closer IL
winter.
To give you a better IDEA of thu
of the earth and moon; let penci
dot represent the moon, circle o
an eighth of an inch in DIANE
ter represent the earth, and cir
Gle with diameter of a little NOR
than thirteen and one half inches
the sun. BY this you can get NOR,
of an idea of the difference in thei
sizes.
The moon has very scaly LOOKING
surface, and astronomers say tina
the moon has no air or water upOl
it's surface: therefore it gives us n
!. heat or light as the sun does.
What Causes An Eclipse.
When the moon passes between tn
; sun and the earth it causes what
called an eclipse of the sun. When tn
earth comes between the moon. an
the face of the sun, this is called
total eclipse of the moon.
