Powers of Ten Solar System Guide Our solar system is an oasis of light, heat, and life in the cold reaches of the Milky Way Galaxy. It consists of a central star the Sun and its family of nine planets, more than 100 moons, millions of rocky asteroids, and billions of icy comets Recent discoveries prove that our solar system is not alone. Astronomers have discovered planets orbiting several other stars. But current technology cannot reveal Earth-like planets the planets that are most likely to harbor life. As far as we know, then, Earth is the galaxy's only inhabited planet.

Powers of Ten Planet Formation The Sun formed from a nebula The inner planets are mostly rock and metal The outer planets are mostly ice and gas Earth's Moon formed separately from the rest of the solar system The solar system was born about 4.5 billion years ago, when something disturbed and compressed a vast cloud of cold gas and dust the raw material of stars and planets. The disturbance may have been a collision with another cloud, or a shock wave from an exploding star. Whatever the cause, the cloud fragmented into smaller, denser pockets of matter, which collapsed inward under the pull of gravity. In perhaps 100,000 years, one of the pockets, called a nebula, condensed into a volume about the size of the present-day solar system. In the dense center of the nebula, a star formed our Sun The newborn Sun was still surrounded by its nebula, which was spread into a thin disk because

Solar System v 1.4 This applet represents the solar system, including the four major moons of Jupiter and our own, and a couple of comets. The On/Off button starts and stops the applet. Because of differences of scale, the inner planets ( Mercury - Mars ) and the outer planets ( Jupiter - Pluto ) are on separate screens. To switch to and from the latter, press the In/Out button. To see/hide the orbits, use the Orbit button. The and buttons allow you to resize the display to convenient dimensions. For a little more excitement, pressing the Ship button will toggle the appearance of a pesky space ship. The planets, their orbits, and their velocities are approximately in scale with each other, but the planet scale is much larger than than the orbit scale, and the sun is not in scale with either. Thanks to Luis Fernandes for his orbit suggestion! The 2000 update modernizes the Java code without changing the operation of the applet.

The Solar System Listen What is the solar system? It is our Sun and everything that travels around it. Our solar system is elliptical in shape. That means it is shaped like an egg. The Sun is in the center of the solar system. Our solar system is always in motion. Nine known planets and their moons, along with comets asteroids , and other space objects orbit the Sun. The Sun is the biggest object in our solar system. It contains more than 99% of the solar system's mass Astronomers think the solar system is more than 4 billion years old.

Star maps though many of these textures have been stitched together directly from multispectral images taken by NASA spacecraft, they should not be used for scientific analysis. Many of these images have blank spots where no images have been taken; some have also been enhanced and slightly altered for aesthetic appeal. For some bodies, no global maps are available at this site yet; some we just haven't explored enough to get any reasonably high resolution images (like Pluto). Maps of the gas giants (Jupiter, Saturn, Neptune, and Uranus) and Titan are merely meant to be representative; atmospheric dynamics will change the body's appearance daily.

Our solar system has 9 planets that orbit a big star called the Sun. (An orbit is the path that a planet moves through.) All the planets orbit the Sun in elliptical paths. (An ellipse is just a stretched out circle.) All the planets take different amounts of time to get all the way around the Sun. Our Earth takes a year to make one complete orbit. In fact, that's how we decided how long a year should be - it's the length of time it takes us to get all the way around the Sun! Also, all the planets spin while they move around the Sun... Just like tops! There is another mess of stuff that orbits the Sun... We call it the Asteroid Belt and it is just a bunch of really big rocks. Here's a picture of all the orbits: If you need to remember the order of the planets, here's a trick: Just look at the first letters of each planet in order, starting with Mercury and working your way out...

The applet below shows the orbits and positions of the planets right now . Click and drag your mouse to tilt or rotate the solar system. Shift+Click zooms in and Ctrl+Click zooms out. Note: The orbits of the planets are shown to scale, but the sun and planets themselves are much larger than scale so you can see them easily. The inner planets (Mercury, Venus, Earth, and Mars), are relatively small and made primarily of rock and iron. The asteroids orbit the sun in a belt beyond the orbit of Mars, tumbling and sometimes colliding with one another. Made mostly of rock and iron, the asteroids may be the remnants of a planet that never formed. The outer planets, with the exception of Pluto, are much larger and made mainly of hydrogen, helium, and ice. Many astronomers believe that Pluto was an interstellar wanderer that was captured by the Sun's gravity and was not an original part of the solar system. The planets move around the sun in fairly circular orbits (i.e., they are elliptical orbits with low eccentricity) Use your mouse to click and drag on the solar system above until you are looking straight down on the planets' orbits. Now zoom in and out to see how all the orbits are very circular, except for Pluto's!
