1 Cosmic Journey: A Solar System Adventure General Information Imagine it a huge spiral galaxy containing hundreds of billions of stars, spiraling out from a galactic center. Nestled deep within one of the great galactic arms is a star. It s a yellow star, average in size and temperature. Yet there is something extraordinary about this star. It lies in the center of a great collection of bodies, all attracted to it by its sheer gravity. This average star is our sun, and the very contributor for the energy that we need to sustain life here on Earth, the third planet in the solar system. What makes up the solar system? At the center of it all is the sun, our nearest star and the brightest object in the sky. It s a ball of gas held together and heated by its own self-gravity. At its center, heat and pressure are so high that nuclear fusion reactions are ignited, releasing even more heat. The energy released at its core takes hundreds of thousands of years to filter out to the sun s surface, where it is then released into space. By comparison, it takes only eight minutes for light from the sun s surface to reach Earth! It s the only star we know of that shelters life among its family of planets. These planets and their moons, and thousands of smaller bodies such as asteroids, comets, meteoroids, and interplanetary dust comprise the remainder of the solar system. The objects in the solar system differ widely from one another but can be sorted into five types. Object Description Terrestrial planets Mercury, Venus, Earth, Mars Rocky Small Few or no moons No rings Asteroid belt objects Asteroids Rocky Jovian planets Jupiter, Saturn, Neptune, Uranus Gas and ice Big Lots of moons Rings Kuiper Belt objects Pluto, comets Ice and rock Oort Cloud objects Comets Ice and rock What are terrestrial planets? Terrestrial planets are the inner planets of the solar system, those that lie closest to the sun. They are small, hard-surfaced planets made of rock and metal with few or no moons and no ring systems. With the exception of Mercury, whose atmosphere is very thin, the terrestrial planets have atmospheres composed of a variety of gaseous chemicals, including carbon dioxide, nitrogen,
2 oxygen, and even sulfuric acid. Each of the terrestrial planets has a similar structure and density, and is composed of a central metallic core and a surrounding mantle. When compared to their larger, gaseous counterparts, terrestrial planets rotate slowly, which makes for longer, but orbit fairly quickly due to their close proximity to the sun. How are Jovian planets different? The Jovian planets are known as the gas giants, large planets whose composition is largely gaseous hydrogen and helium. These planets Jupiter, Saturn, Uranus, and Neptune are home to turbulent atmospheres and no solid surface. They have compressed cores and thick atmospheres mottled by fierce storms and powerful winds. The gas giants lie beyond the asteroid belt, at distances far greater than the inner planets. In comparison to their inner planetary cousins, the gas giants rotate at fast speeds, leading to short. Elaborate rings of debris circle each of the four Jovian planets, though Saturn s are the most spectacular. More than 100 moons orbit these large planets, two of which are larger than Mercury, and several larger than Pluto. What else can be found in the solar system? What remains in the solar system can be grouped into three categories. First are asteroid belt objects, a group of rocky objects that orbit the sun but are small like moons. They are simply chunks of rock that never quite pulled it together to become planets and are probably left over from the time of the solar system s formation. The asteroid belt can be found between the orbits of Mars and Jupiter and is home to s of objects ranging in size from 60 miles to 20 feet in diameter. Beyond the orbit of Neptune are Kuiper Belt objects. These objects, including Pluto and many short period comets, are composed mainly of rock and ices such as methane, ammonia, and water. The Kuiper Belt is very similar to the asteroid belt, though it is much larger, at least 20 times as wide. Much like the asteroid belt, the Kuiper Belt is home to objects probably left over from the time of solar system formation, pieces of material that didn t form into a planet. Beyond the Kuiper Belt lies the Oort Cloud, home to comets made of ice and rock. Considered to be the outer edge of the solar system, the Oort Cloud extends 18 trillion miles from the sun. The most famous of the Oort Cloud objects is Sedna, a reddish object estimated to be three-fourths the size of Pluto. How many planets are in the solar system? Since 1930 when Clyde Tombaugh discovered Pluto, it has been widely accepted that there are nine planets in the solar system. Recently, scientific discoveries in the outer solar system have lead to confusion among the members of the scientific community about the definition of a planet. Some astronomers believe that Pluto is not a planet and should be considered a dwarf planet. The general definition of a planet is any celestial body (besides comets or satellites) that orbits around a star. Pluto, like the other planets, is round and orbits around the sun. It even has a satellite of its own. However, it is much farther out from the sun and has a strange, tilted, oval-shape orbit. It is also much smaller than the other planets in the solar system. New discoveries have shown many more of these small, distant, icy objects similar to Pluto beyond its orbit. If Pluto is considered a planet, then these other objects would also qualify for planet status. These factors have contributed to the confusion among astronomers about Pluto s status as a planet. Yet the debate remains and probably will for some time to come. Is Pluto a planet or a dwarf planet?

Life as we know it needs three things: chemicals based on carbon, liquid water, and energy. Earth s position in the solar system is the perfect location to provide for these three things. Its distance from the sun allows just the right amount of heat to maintain the liquid state of water. This distance allows for just the right amount of heat and light from the sun for a pleasant climate. The sun s energy warms the planet, creates our weather, and circulates ocean currents. Are there other places in the solar system that might harbor life? There are many other locations in the solar system where scientists are now looking for life or conditions that may have supported life in the past. Though scientists have studied the possibility of life s existence on gas giants in the outer solar system, most have concluded that the conditions of the atmospheres of these planets are much too unstable to support life, despite their having the ingredients possible to form it. However, scientists have not given up on their search for life within the solar system. Most of the locations of interest now are on moons of other planets. For instance, Neptune s moon Triton is known to have organic material, but all of its water is frozen and it is too far away from the sun to receive the energy needed to support life. Saturn s moon Titan is also a hot spot for scientists who search for life. Titan is home to a thick nitrogen atmosphere made hazy by chemicals called hydrocarbons. Underneath this thick atmosphere is a hard, icy landscape where chemicals rain from the sky carving the landscape with gullies and liquid lakes of methane. Scientists think that this moon is a lot like Earth was in the beginning with lots of organic material. Yet the surface is still much too cold for liquid water or for the conditions necessary for life.
4 Another of Saturn s moons, Enceladus, was recently discovered to be releasing water into space from cracks in its crust, in much the same way as geysers on Earth spout water into the air. The strong gravitation pull of Saturn or some radioactive elements are keeping things warm enough inside to melt ice into liquid water. This liquid water could possibly make a home for simple forms of life. Jupiter s moon Europa is another source of study for scientists. Much like Enceladus, Jupiter s gravitational pulls on Europa creates a warm interior that may be warm enough to harbor an ocean of liquid water beneath its icy crust. If the moon does have liquid water, a source of heat, and organic materials, it could possibly be home again to simple forms of life. What are moons? A moon or satellite is a body that orbits a planet or another body larger than itself. There are about 240 known moons in the solar system. Jovian planets possess extensive moon systems, where terrestrial planets have few or no moons. The largest moons in our solar system include Earth s moon, Jupiter s four Galilean moons (Io, Europa, Callisto, and Ganymede), Saturn s moon Titan, and Neptune s moon Triton. Moons are as diverse as the planets in which they orbit. Some have atmospheres, others are dead, crater-pocked wastelands. Others are home to active volcanoes while still others contain geysers that spout water into space. How old is the solar system? Just more than 4.5 billion years ago, an incredible event happened that has shaped life as we know it. This event, the formation of the solar system, is a mystery about which scientists can only speculate. Using radiometric dating of meteorites, scientists have hypothesized that the sun was born in a nebula about 4.6 billion years ago. Based on the trends in the nature of the planets compared to their distance from the sun, we now believe the planets were also formed at the same time as the sun. What does the future look like for the solar system? Scientists have estimated that the sun is about halfway through its life. In another 5 billion years or so, the sun will run out of nuclear fuel in its core, and it will become unstable, evolving to a red giant and eventually puffing off its outer layers as a planetary nebula, leaving only a white-dwarf core behind. The inner planets may be completely destroyed and conditions will change on the outer planets. Perhaps some of the now-frozen icy moons will even become warmer places where life can thrive in this distant future.
