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.

Read More At: Solar System Live by Fourmilab Welcome to the Planets by NASA's JPL Going Wild! by NASA's Space Sciences News Glossary: asteroid eccentricity AU Liftoff Home Explore the Solar System Our solar system consists of the sun, the nine planets and their moons, asteroids and comets. 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!

88. How Big Is The Solar System? Also known as The Earth as a Peppercorn. A scale model of the solar system. http://www.noao.edu/education/peppercorn/pcmain.html

THE THOUSAND-YARD MODEL or, The Earth as a Peppercorn Universal Workshop PO Box 426 Middleburg, VA 20118-0426 ISBN 0-934546-21-5 This is a classic exercise for visualizing just how BIG our Solar System really is. Both the relative size and spacing of the planets are demonstrated in this outdoor exercise, using a mere peppercorn to represent the size of the Earth. Guy Ottewell has kindly given permission for this electronic presentation of The Thousand-Yard Model; his exercise is presented in its original form, indexed with a few anchors to help you find you way around the large file. We also include a catalog describing several Ottewell publications. Image of the planets courtesy of NASA Introduction Pacing off the Solar System Additional Notes ... Numerical Summary Introduction Can you picture the dimensions of the solar system? Probably not, for they are of an order so amazing that it is difficult either to realize or to show them. You may have seen a diagram of the Sun and planets, in a book. Or you may have seen a revolving model of the kind called an orrery (because the first was built for an Earl of Orrery in 1715). But even the largest of such modelssuch as those that cover the ceilings of the Hayden Planetarium in New York and the Morehead Planetarium at Chapel Hill-are far too small. They omit the three outermost planets, yet still cannot show the remaining ones far enough apart. The fact is that the planets are mighty small and the distances between them are almost ridiculously large. To make any representation whose scale is true for the planets sizes and distances, we must go outdoors.

89. Chaos Article about the development of the theory and its astromomic insights. http://www.geocities.com/paul_bt@sbcglobal.net/essays/ChaosandSolarSystem4.htm

Chaos and the Solar System Paul Trow Mathematical theories do not usually get much public attention. A recent exception is the theory of chaos, which emerged on the scientific world in the 1970’s, and has since received extensive coverage by the media and in a number of books aimed at a general audience. The term “chaos” has even made its way into several popular science fiction movies. Part of the fascination with this theory has to do its claim that chaos – which is inherently more interesting than order - is a pervasive feature of the world around us. Chaos, we are told, is responsible for the unpredictability of the weather and the fluctuations of the stock market. We can observe it in ecological systems, the rhythms of the human body, and the turbulence of a mountain stream. Surprisingly, although chaos is all around us here on Earth, the mathematician Henri Poincare first discovered it, late in the nineteenth century, in the mathematics underlying the solar system. Before explaining just what Poincare discovered, let us recall a little of the background the background that led up to it. In a sense, chaos theory is as a belated reaction to the principle of determinism, which has dominated science for over three hundred years. Newton established this principle through his second law of motion, force equals mass times acceleration, from which it follows that if we know all of the forces acting on a system, we should – at least in theory - be able to predict how it will evolve over time. Determinism gave rise to the metaphor of the clockwork universe, which, when once wound up, will evolve forever in a predetermined manner.

95. A Scale Model Of The Solar System online Java applet This 3d solar system applet can be rotated and zoomed with the mouse. Below it are links to other online gravity simulators and http://burtleburtle.net/bob/physics/solar.html

This applet is the obligatory scale model of the solar system. Distance is in AUs, velocity in AUs per hour, mass in units of 10 pounds, yielding G=1.2944x10 . Initial positions are accurate to about 5 digits. The simulation doesn't account for relativity, oblateness of the sun, solar winds, asteroids, galactic gravitational flux, and any number of other things. The numbers in the corner count how many displays have been done and the fractional error in energy conservation. It starts 1am on January 1, 1999. To start or stop, click. To spin around the sun, click in the middle and drag. To rotate and zoom, click near the edges and drag. The sun remains in the center; there are no controls yet to change that, or to change the distance from the sun. I also have and applet description , some online references for how to build a solar system simulator, a set of stable orbits filling 3-space , a page exploring gravitation with Java , a simulation of Cruithne , and Klemperer rosettes sun mercury venus earth+moon mars jupiter saturn uranus neptune pluto The US Navy provides the coordinates of all planets now, and at any other time give or take a century. I used this for my initial coordinates. (Position is at 1am on January 1, 1999, and velocity is half of 2am minus midnight.)

Also available is a view of the innermost region of the solar system . The plot is of the same form as the plot on this page. An animated version of this plot is available from our Animations page. This plot must not be reproduced without the express written consent of the Minor Planet Center Jupiter Trojans , here colored deep blue. Numbered periodic comets are shown as filled light-blue squares. Other comets are shown as unfilled light-blue squares. In this view, objects in direct orbits (most of the objects in this plot) move counterclockwise and the vernal equinox is towards the right. (The equinox directions are the direction of the sun as seen from the earth.) The plot is correct for the date given at the bottom of the plot. Back to minor planet lists and comet lists Credits.
