"The heavens declare His righteousness, and all the people see His glory." Psa. 97:6.
High in the sky, 267-million miles from the earth, is the planet Jupiter. This largest of all planets (that we know about) makes its orbit 480-million miles away from the sun at a speed of 28,000 miles per hour. It is heavier than all the other planets put together, as large as 13 earths, and its surface is 120 times as great. Its night and day of only about ten hours contrasts with the earth's 24-hour revolution.
In 1979 the American "Voyager" spacecraft flew by this great planet and discovered that its actual surface could not be photographed because a thick covering of clouds always hides it. Further spacecraft studies are planned in the near future.
Jupiter can be seen from earth by using a strong telescope. Its pink and salmon clouds are a beautiful sight as it shines brightly on a clear night. Perhaps the most interesting and puzzling thing about Jupiter is its 20,000-mile long red spot which seems to drift and change color from time to time and even temporarily disappears. Scientists think it may be caused by volcanoes, but do not really know. It may be caused by the 300 mile per hour whirling storms that scour its surface.
Because Jupiter is almost five times as far from the sun as is the earth, it is extremely cold, and nothing could live on it. No water could exist in its -200° F. temperature. Also, its atmosphere (poisoned by chemicals that erupt from inside it) could never support life even for one moment. Men, properly dressed in space suits, have walked on the moon, but none will ever walk on Jupiter!
This reminds us of the wisdom of God, the Creator, in placing the earth at exactly the right distance from the sun (approximately 93 million miles) to provide the correct amount of heat and light for all the creation He has placed here. David, no doubt thinking of this, said "The heavens declare the glory of God; and the firmament showeth His handiwork. Day unto day uttereth speech, and night unto night showeth knowledge." Psa. 19:1,2.
Jupiter is one of the four, major outer planets of the sun, the others being Uranus, Saturn and Neptune. Not one of them could sustain any form of life. Only the earth was formed for that purpose. Jupiter's attractiveness as a marvel of God's creation includes one large ring around it, discovered by Voyager's trip, plus the fact that it has 16 moons circling it, some with volcanoes erupting on them. Twelve of them circle clockwise and four counter-clockwise.
As we gaze up into the starry sky, let us always remember that all are kept in perfect order by the One who placed them there. In their beauty and the pattern of their orbits, which is always the same, He has taken great pleasure. We are privileged to share their beauty with Him in a small way.
