Think what a difference! Two hundred and forty thousands are only a small part of a single million; for a million is a thousand thousands. If you have one thousand beads in a heap, you would need one thousand of those heaps to make a million beads. And when you get to the idea of what is meant by a million, you have to remember that the Sun’s distance is ninety-two times _that_ number of miles. After all, we cannot comprehend these figures; they are too bewildering. We may talk of thousands and millions of miles, but we do not _see_ them in our minds. The chief thing to do is to gain some notion of one distance side by side with another: and here the three balls all help us again. Picture to yourself the tiny Moon-ball, as big as a large grape, and the Earth-ball, as big as a small cocoa-nut; and in your mind put the two _ten feet_ apart. There you have the sizes and the distance of the Earth and the Moon brought down from thousands of miles to inches. Then picture to yourself the Sun, as big as a balloon--the length of six tall men through its middle--and in your mind put that balloon _three quarters of a mile_ away from the small Earth and Moon. Somebody will tell you of a house or a place about three-quarters of a mile away from your house, if you ask. Now do you see how great the difference is between the distance of the Sun from us and the distance of the Moon? Close upon four thousand feet off, instead of only ten feet off! Almost thirteen hundred yards, instead of a little over three yards! Ninety-two millions of miles, instead of two hundred and forty thousand miles! The _kind_ or _quantity_ of difference between the two is the same, whether we reckon it in inches or feet, in yards or miles, in hundreds, or thousands, or millions of miles. The Moon and Sun are quite unlike in their way of shining. Our little Moon has no brightness of her own. She only shines when and where the Sun shines upon her. But the radiance of the Sun is his own; it is a part of himself. He shines because it is _in_ him to shine; it is his nature to shine. He is brilliant all round, not on one side only. If the Sun were destroyed the Moon would shine no longer. But if the Moon and the Earth and all the Planets came to an end it would make no difference in the brightness of the Sun. The Sun’s shining is like the shining of the Stars, not like that of the Earth and the Moon: for the Sun himself is a Star; one Star among millions of Stars. He only looks so much larger and brighter than other Stars because he is so much nearer than they are. Our Earth and Moon are not stars; they are planets, or worlds, travelling round the Sun, and belonging to him. They are not hot bodies, glowing with their own light; but cool and dark bodies, bright only when the Sun shines on them. Moonlight, and also Earthlight--which we, living on the Earth, cannot see--are both really reflected Sunlight.
