SEPTEMBER SCIENCE CO-OP OUTER SPACE & THE SUN
Genesis 1:3 Then God said, "Let there be light"; and there was light.
Genesis 1:16 Then God made two great lights: the greater light to rule the day...
God spoke and light, as we know it, came to be. The sun, earth's closest star, is a great ball of extremely hot gases.

Soaring Through Our Solar System By Laura G. Smith
-------------------------------------------------------------------------------- 1 Five, four, three, two, one... BLAST OFF! Come along as we explore our solar system! If we were flying high above the Earth, what would you see? The biggest, brightest thing you would see is the sun. You would also see many objects traveling around the sun, including the Earth and its moon! 2 The sun, planets, and moons are all part of our solar system. The sun is a huge star in the middle of the solar system. It is the only star we can see during the day. The sun is much brighter than the stars we see at night, because it is much closer to the Earth. It is made of gases that are released in the form of light and heat. 3 The planets are all different sizes. Pluto, the smallest planet, is tinier than the Earth's moon. Jupiter is the largest planet. It is eleven times wider than the Earth! All nine of the planets are much smaller than the sun. If you had a hollow ball the size of the sun, you could fit one million balls the size of the Earth inside it! 4 All of the planets in our solar system move around the sun in an oval path called an orbit. This path is shaped something like an egg. The sun has a strong force that pulls all of the planets toward it. This force, called gravity, is what makes the planets stay in their orbits. As each planet orbits the sun, it is also spinning around like a top. This spinning is called rotation. Each planet rotates at a different speed. It takes Jupiter less than 10 hours to rotate one time, but it takes Venus 243 days! 5 The planets can be divided into two groups. The first group is called the inner planets. The second group is the outer planets. The inner planets-Mercury, Venus, Earth, and Mars-are smaller and are made of mostly rock and iron. Jupiter, Saturn, Uranus, and Neptune make up the outer planets, which are much larger. They are made mostly of hydrogen, helium, and ice. Pluto is the smallest planet and the farthest from Earth. Because it is so far away, scientists don't know very much about it. Some scientists think it shouldn't even be included as one of the nine planets. 6 There are more than 120 moons that orbit the planets in our solar system. Some planets, like the Earth, only have one moon. Other planets, like Jupiter and Saturn, have as many as 30 moons traveling around them! 7 Besides the nine planets and their moons, there are thousands of other, smaller objects in our solar system. These are small chunks of rocks called asteroids. The tiniest asteroids are less than a mile wide. The largest is over 600 miles wide.

Small chunks of iron and rock that break away from asteroids are called meteoroids. Many meteoroids fall close to the Earth. Most of them burn up before they reach the Earth's surface. Meteoroids that fall through the sky like streaks of light are called meteors or "shooting stars." When a meteoroid is found on the Earth's surface, it is called a meteorite. Scientists can study meteorites to learn important facts about our solar system. 9 Comets are another part of our solar system. They travel around the sun just like the planets. A comet looks like a fuzzy star with a long tail. It is made of frozen gases, ice, and bits of dust. Every comet takes a different amount of time to make a full orbit. One famous comet called "Halley's Comet" takes about 77 years to orbit once around the sun. 10 When the telescope was invented in the early 1600's, scientists began to learn much more about the sun, planets, moons, asteroids, meteoroids, and comets that make up our solar system. A long time ago, before we had telescopes, people thought the Earth was in the center of space and that the sun and other stars orbited around it! 11 Today, with the help of spaceships and other equipment, man is learning even more about our amazing solar system!

Our Solar System By Laura G. Smith
-------------------------------------------------------------------------------- 1 If you look up the word "solar" in your dictionary, you'll find its basic definition reads something like: "of the sun," or "relating to the sun." System is defined as: "a set of things or parts forming a whole." When you consider the meanings of these words, there is indication that the sun plays a major role among this group of celestial bodies we call the "solar system." 2 The sun is, in fact, at the center of this massive system. There are nine major planets and their satellites, asteroids, comets, dust and gases that are continually traveling around the sun. With a mass that is 750 times as great as that of all of the planets in the solar system combined, the sun has a strong gravitational pull that keeps the other objects in orbit around it. 3 As the planets revolve around the sun, the sun revolves around the center of the Milky Way Galaxy. The Milky Way, which has a circular shape, is made up of dust, gases, planets, and about 100 billion stars. The sun, planets, and other bodies and gases that make up our solar system are only a small speck in this huge galaxy! 4 The nine planets of the solar system can be divided into two groups referred to as the inner planets (also called terrestrial planets) and the outer planets (or major planets). The inner planets; Mercury, Venus, Earth, and Mars, are small and are composed of mostly rock and iron. Jupiter, Saturn, Uranus, and Neptune make up the outer planets, which are much larger and consist mainly of hydrogen, helium and ice. Because Pluto is the farthest planet from Earth, astronomers know very little about it. Some believe it should not even be considered as one of the major planets. More than 120 natural satellites (also called moons) orbit these various planets in our solar system. 5 Asteroids (also called planetoids) are small bodies that orbit the sun, mostly between Mars and Jupiter, in what is referred to as the Asteroid Belt or Main Belt. Astronomers first observed asteroids in the early 1800's with the aid of telescopes. There are more than 20,000 asteroids ranging in size from Ceres, which has a diameter of 623 miles, to bodies that are less than 1 mile in diameter. The Asteroid Belt also includes large amounts of dust that astronomers believe were created by collisions between asteroids. 6 Small chunks of iron and rock that break away from colliding asteroids are called meteoroids. Many meteoroids fall to the earth's atmosphere, but most are burned up by friction before they reach the earth's surface. 7 Meteoroids that fall through the atmosphere, appearing in the night as streaks of light, are called meteors or "shooting stars." Those that are found on the earth's surface are known as meteorites. As scientists have studied meteorites, they have learned valuable information about the ancient conditions of our solar system. The surfaces of Mercury, Mars, and several satellites of the planets (including the earth's moon) show signs of having been "attacked" by asteroids during the early history of the solar system. 8 Some meteors and interplanetary dust (dust that is in between or near the planets) may come from comets. Comets generally have three parts: a solid nucleus or center, which is often no bigger than a few miles across; a round coma, or head, that surrounds the nucleus and is made up of dust particles and frozen gases; and a long tail of dust and gases that escape from the head. Most comets orbit the sun near the outer edge of the solar system. When a comet is drawn closer to the sun, it releases its dust and gases displaying a spectacular, shining tail. The famously known Halley's Comet appears every 75 years. Its most recent appearance was in 1986. 9 Solar wind is another part of the solar system. It is a very thin gas that streams outward constantly from the surface of the sun and through interplanetary space. The particles in solar wind travel past the earth at speeds of about 300 miles per second. This wind also shapes the tails of comets and leaves its particles in the lunar soil. Samples of these particles were brought back from the moon's surface by manned United States Apollo spacecraft. 10 Since the invention of the telescope, man has greatly increased his knowledge of our solar system. It almost seems silly to realize that ancient astronomers once believed that the earth was the center of the universe and that the sun and all of the other stars revolved around the earth! Little by little astronomers are solving mysteries about the universe. As more powerful tools and techniques are developed, astronomers will become even better equipped to satisfy our curiosity about the amazing stars and planets that decorate our sky.
