Countless worlds are ever whirling Through the boundless realms of space, And the hand of Him who made them Keeps each one in its true place.
Reference to "the planetary system" means the nine heavenly bodies (including our earth) that are grouped around the sun and held in their individual orbits by its great gravitational pull. The sun maintains this control because it is 700 times more massive than all the planets and their moons put together. But it is, of course, the Creator who has arranged this grouping and has kept its force operating since the first day of creation-"upholding all things by the word of His power." Heb. 1:33Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high; (Hebrews 1:3).
In outer space there are untold numbers of moons, but it is only those of "our planetary system" that are familiar to astronomers. In the language of these experts, planets are satellites of the sun, and moons are satellites of the planets.
There are more than 50 known moons and more being discovered with improved instruments. Every planet does not have a moon, but some have two or more. Mars and Neptune each have two, Uranus at least a dozen, Jupiter has 15 and Saturn 21. The earth's moon is just average size. Some are smaller and some almost twice as large.
Many, like ours, are covered with mountains, plains and valleys. Some look like huge snowballs with icy coverings while others have volcanoes erupting on them. They are all interesting examples of the wonders of God's creation.
Each moon follows its own orbit, century after century, keeping its exact position over its planet, never crashing into it or other moons. But the most extraordinary thing is that some circle their planets in one direction and some in another. Only one of the nine planets, Venus (which, incidentally, does not have a moon), orbits around the sun in a clockwise direction. The other eight all travel in the opposite direction. It would almost seem that Venus would interfere with the others, but the Creator does not allow that to happen.
Most moons travel the same direction as the eight planets, but not all. Neroid-one of Neptune's moons-goes in "reverse," but its companion, Triton, moves clockwise. The five moons of Uranus all circle it in the "reverse" direction. But strangest of all are the moons of Jupiter-eleven move around it in the counter-clockwise motion, but the other four in just the opposite direction! Did the Creator make an error in this? No. If it had been an error they would have crashed into each other long ago. We do not know why He made this interesting arrangement, but we do know He took pleasure in doing so, and that He has each of them under His control.' "His work is perfect." Deut. 32:44He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he. (Deuteronomy 32:4).
Are you letting Him be the Guide and Protector of your present life? Have you made Him your Savior to take care of your eternal life as well?
