Solar System From Wikipedia, the free encyclopedia Jump to: navigation search This article is about the Sun and its planetary system. For other systems, see planetary system and star system Planets and dwarf planets of the Solar System. Sizes are to scale, but relative distances from the Sun are not. The Solar System [a] consists of the Sun and the astronomical objects bound to it by gravity , all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. Of the many objects that orbit the Sun, most of the mass is contained within eight relatively solitary planets [e] whose orbits are almost circular and lie within a nearly flat disc called the ecliptic plane . The four smaller inner planets, Mercury Venus Earth and Mars , also called the terrestrial planets , are primarily composed of rock and metal. The four outer planets, the gas giants , are substantially more massive than the terrestrials. The two largest, Jupiter and Saturn , are composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune , are composed largely of ices , such as water, ammonia and methane, and are often referred to separately as "ice giants".

Directory Solar System Compiled By: Editor Lesson ideas for teaching about the solar system Solar System Posted by: Jennie #30421 Have you considered introducing this unit based upon the Earth and its place in the solar system? Since you have second graders (I don't know how advanced they are) you might want to start here and introduce the rest of the solar system based upon its relation to the position of the Earth. Just an idea. I teach third and our focus is supposed to be on the sun and moon and their relation to the Earth, but I end up teaching about the entire solar system. The kids are always really in to it, and why waste a teachable moment? Just do whatever your gut tells you about how much to teach them, but start with something they know. Also a great time to talk about seasons and weather. AIMS has a great book about the solar system for grades 4-8, however I do use some of the activities for my third gra... View Item (172 words) Solar System ideas Posted by: Amy #85003 We are just finishing up a solar system unit in my second grade class. Some of the activities we did with the kids included having them cut out and paste the planets on a long black piece of paper in order and color them according to their colors. We also were and still might do a constellation lesson in which we turn off all the lights and make it as dark as possible and them have a pieces of construction paper with holes cut out in the shape of various constellations such as the big dipper and Orion's belt. We also kept a space log and everyday that we studied space we would write on an overhead what they learned and they would copy it on their own log sheet. We also had them make solar system mobiles in the shape of a sun, which they decorated and then we punched holes through note card...

Home Gallery Introduction Prints Entire Gallery ... Comets The Solar System Since ages mankind has gazed upon the night sky. The majority of the stars visible on the heaven appeared static to the ancients, but there were a few stars that appeared to change their position in time. They were called the wanderers , or the planets For thousands of years people thought that the planets, moons and Sun revolved around the Earth, and that the Earth was the center of the universe. When telescopes were invented in the seventeenth century, people began to question if this really was true. Some people who claimed that the planets did not revolve around the Earth, but rather the Sun, had to pay with their life for this, such as Giordano Bruno who was sentenced to be burned to death. It is now known by astronomers that the moons orbit their planets and the asteroids, planets and comets orbit the sun. This conception of the world is called heliocentrism 4.6 billion years ago, the solar system was created through the collapse of a nebula. Perhaps this collapse was triggered by the passage of a nearby star, or maybe a nearby supernova explosion. Today the solar system consists of the sun at the centre, four

The Solar System The words " solar system " refer to the Sun and all of the objects that travel around it. These objects include planets, natural satellites such as the Moon, the asteroid belt, comets , and meteoroids . Our solar system has an elliptical shape and is part of a galaxy known as the Milky Way. The Sun is the center of the solar system. It contains 99.8% of all of the mass in our solar system. Consequently, it exerts a tremendous gravitational pull on planets, satellites, asteroids, comets, and meteoroids. Astronomers believe the solar system formed 4.5 billion years ago. However, they differ in their beliefs about how the system formed. Some believe the whole solar system formed from a single flat cloud of gas, while others believe it formed when a huge object passed near the Sun, pulling a stream of gas off of the Sun. Astronomers theorize the planets then formed from this gas stream.

Our Solar System includes the Sun together with the eight planets and their moons as well as all other celestial bodies that orbit the sun. Besides the sun, 8 planets and their moons, our Solar System contains billions of other objects and extends far beyond the outermost planets . There are several hundred thousand asteroids revolving around the Sun. Most have orbits between Mars and Jupiter. Also, in addition to the more than 800 comets we have recorded passing through the inner part of the solar system, there are billions more lying in the area surrounding the solar system. They are in the disk of debris known as the Kuiper belt and the cloud of comets known as the Oort cloud. Next, to a smaller scale, there are countless meteoroids (some of which include cometary debris and fragments from the collision of larger bodies), some of which approach Earth's orbit closely enough to be known as near Earth objects. Finally, billions of objects (many the size of a speck of dust) cross through our atmosphere as meteors or micrometeoroids each day, usually completely unnoticed.

Our system consists of the sun and the planetary bodies orbiting it such as the eight (formerly nine) planets , three dwarf planets , about 160 known planetary satellites ( moons ), and countless asteroids . The solar system also consists of many various icy bodies, and vast amounts of nebula, gas and dust known as the interplanetary medium. Besides the sun, Earth, and Earth's moon, many objects in our solar system are visible to the unaided eye. These objects include the planets Mercury, Venus, Mars, Jupiter, and Saturn; the brightest asteroids; and occasional comets and meteors. Many more objects in the solar system can be seen with telescopes. Contents Characteristics Sun Planets Moons ... Related Links Characteristics Sun Main Article: Sun The sun is the largest and most important object in our solar system. It is the closest star to Earth and thus the most prominent star in our galaxy. From the sun's center to its surface, it is about 109 times the radius of Earth. Some of the streams of gas rising from the solar surface are larger than Earth. It contains 99.8 percent of the solar system's mass (quantity of matter). The sun provides most of the heat, light, and other energy that makes life possible.

People Directory Faculty Postdocs ... Site Map Solar System Research Sun Solar System Stars and ISM Galaxies ... Adaptive Optics Maintained by W-W Why is the Solar System the way it is? Many of the properties of planet Earth, including its size, its orbit, its temperature, and its composition are the direct result of processes that occurred 4.5 billion years ago in a collapsing, rotating cloud of interstellar gas and dust. Planetary astronomers at IfA are trying to discover what these processes were. As the interstellar cloud shrank to form the solar nebula, its gas density grew, allowing dust grains in the cloud to coalesce into planetesimals that in turn grew to form planets. The planetesimals near the Sun were made of rock and metal. Those farther from the Sun, where the temperature was cold enough and the gas was thin, were made of ice particles and other frozen molecules along with dust grains and trapped gases. Billions of these primitive objects still exist beyond the orbit of Neptune, though they are very hard to find and study. These small icy objects may tell us as much about the origin of the solar system as do the major planets. The deep freeze of the outer reaches of the solar system has preserved compounds from the interstellar cloud that produced the Sun and the planets. It is a rich place to look for clues about our origins.
