lions of miles their light travels, still retaining something of 
their majesty in the twinkling light which indicates their power. 
(After further details he continued.) 
The planet, like the earth we inhabit, is not a luminous 
body. It gives simply the light it receives from the sun. The 
sun is the centre around which the planets revolve. ‘The 
Earth is one, Jupiter is another. In mythology or the history 
of the pagan gods, the great God of thunder and lightning was 
called Jupiter or Jove. You have heard the expression, “‘ By 
Jove.” 
In the planetary system the name Jupiter has been given 
to the giant planet. This planet, Jupiter, is so immense that 
were you to combine Saturn, the earth, and all the other planets 
it would still surpass them all in size. It is close on 1,300 
times as large as our earth and almost half the size of the sun. 
t is the brightest and largest heavenly body that the naked eye 
can see at night except the moon. But put Jupiter where the 
moon is and its disc would extend across one-half of the 
heavens. 
Again, if it appears larger and brighter than the stars, it 1s 
because it is only a small fractional distance of the stars from 
us. It is 483,000,000 miles from the sun and 400,000,000 from 
us. Let us make our first trip there through the telescope.

Compare with earth’s size. You will see here at a glance 
the comparative sizes of the Earth, the planet we inhabit, with 
the size of Jupiter. It would require 1,300 Earths to make a 
planet equal to Jupiter in size. Now, considering that the 
earth is no small globe, remembering that it is some 25,000 miles 
around the Earth, by multiplying this by 1,200 you will be able 
to fancy what a huge body is revolving over your head as you 
gaze upon the bright and beautiful star Jupiter. 
The great pleasure which Jupiter allows us by its brilliant 
appearance in the Zodiacal constellations we do not reciprocate. 
Should Jupiter be inhabited neither our own existence nor even 
the existence of the Earth is suspected by those inhabitants. 
The Earth, we might say, is comparatively invisible to the in-
