THE SUN AND PLANETS.

The planet Venus had been shining brilliantly evening after evening. “Why, father,” said the boy, “does Venus shift her place so rapidly among the stars?

Because she has to travel round the sun, as the world and other planets do.

And is the world really a planet, looking like a star to the people of Venus?

Yes; and not visible at all to those of the distant planets, which are all so much nearer to us than the nearest of the fixed¹ stars. Some of the planets you could not see without the telescope, and you see none of the asteroids².

What are they?

Little planets, over eighty in number, perhaps the shattered parts of an exploded planet, travelling along the old road, and keeping a circle between Mars and Jupiter.

Then they are not like the comets, which run everywhere, getting in everybody’s way?

You are slandering³ the comets. These shadowy bodies, with tails of light, travel in longer ovals or ellipses⁴ than the planets. We see them when they turn round the sun, which is near one end of their orbit, but they disappear afterwards in the great distance of their curve.

Well, I can see some use in the sun to us, but very little in the planets and other stars, and none in the comets.

You must not selfishly judge of the good of things by the use you can make of them. The[Pg 70] extensive granite⁵ ranges were not made merely for man’s building materials, nor the stars for a gaze through a telescope. As the world existed many millions of years without man, so have the stars. In another world we may know more of the why and because of God’s creation.

May not the planets and other stars be inhabited by folks like ourselves?

Not quite, my son, replied Mr. Marple, though God can make intelligent beings to praise Him, who would be adapted to any atmosphere or condition of the stars.”

In the evening the captain lent James a book, from which he copied the following table of the Eight Planets—their distance from the sun, their times of revolution round the sun, and their size:—

     Distance.    Time.    Diameter.
     Miles.              Miles.
 
Mercury    37,000,000    2    months    3100
Venus    69,000,000    7?    ”    7900
Earth    93,000,000    1    year    7920
Mars    146,000,000    2    years    4000
Jupiter    494,000,000    12    ”    92,000
Saturn    906,000,000    30    ”    75,000
Herschel        1820,000,000    80    ”    36,000
