An Overview of the Solar System Orbits The solar system consists of the Sun ; the eight official planets, at least three "dwarf planets", more than 130 satellites of the planets, a large number of small bodies (the comets and asteroids), and the interplanetary medium. (There are probably also many more planetary satellites that have not yet been discovered.) The inner solar system contains the Sun Mercury Venus Earth and Mars The main asteroid belt (not shown) lies between the orbits of Mars and Jupiter. The planets of the outer solar system are Jupiter Saturn Uranus , and Neptune Pluto is now classified as a dwarf planet): The first thing to notice is that the solar system is mostly empty space. The planets are very small compared to the space between them. Even the dots on the diagrams above are too big to be in proper scale with respect to the sizes of the orbits. The orbits of the planets are ellipses with the Sun at one focus, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth's orbit) . The ecliptic is inclined only 7 degrees from the plane of the Sun's equator. The above diagrams show the relative sizes of the orbits of the eight planets (plus Pluto) from a perspective somewhat above the ecliptic (hence their non-circular appearance). They all orbit in the same direction (counter-clockwise looking down from above the Sun's north pole); all but Venus, Uranus and Pluto also rotate in that same sense.

Skip to Navigation The Solar System Our solar system is an oasis of light, warmth, and life. It is home to one star, a handful of planets, more than a hundred moons, millions of rocky asteroids, billions of icy comets and all the known life in the universe. And it is a realm that we are still learning about as we begin to explore it in greater detail. Sun Explorations Find out about scheduled missions to our solar system neighbors in the coming year.

Remnants from the Beginning The Solar System The Solar System: Home Sweet Home Do all planets orbit the Sun in the same direction? While not all of the planets rotate on their individual axes in the same direction Uranus and Venus both rotate opposite to the other six planets the planets are in agreement as to which way to go. The shared motion is an artifact of the formation of the solar system from a giant rotating gas cloud 4.5 billion years ago. As for the reversed, or retrograde, spin of Uranus and Venus, scientists are divided as to the cause. Most subscribe to the theory that early in their histories, these worlds were subjected to massive collisions with planetary-sized objects, so powerful they reversed the planets original direction of rotation and in the case of Uranus, knocked it almost completely sideways.

We all must question our very existence at some point in our short lives, and seek answers through either religion or perhaps science. For me the latter must hold the answers, yet I am sure that in my lifetime at least there will be no definitive answer as to 'why' we exist. The best description of the human race is ideally summed up in the film 'The Matrix'..... "I tried to classify your species and I realized that you are not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not, you move to an area and multiply, and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern...a virus. Human beings are a disease, a cancer of this planet...you are a plague."

Small Solar-System Bodies The title The Nine Planets is somewhat misleading. In addition to the (eight) planets and their satellites the solar system contains a large number of smaller but interesting objects. There are thousands of known asteroids and comets and undoubtedly many more unknown ones. Most asteroids orbit between Mars and Jupiter . A few (e.g. 2060 Chiron) are farther out. There are also some asteroids whose orbits carry them closer to the Sun than the Earth (Aten, Icarus, Hephaistos). Most comets have highly elliptical orbits which spend most of their time in the outer reaches of the solar system with only brief passages close to the Sun. And there is a large and important class of Trans-Neptunian Objects or Kuiper Belt Objects (including Pluto) that orbit (mostly) beyond Neptune. The distinction between comets and asteroids is somewhat controversial . The main distinction seems to be that comets have more volatiles and more elliptical orbits. But there are interesting ambiguous cases such as 2060 Chiron (aka 95 P/Chiron) and 3200 Phaethon which seem to share some aspects of both categories.
