Interactive Solar Systems and Star System Pages

  http://www.shatters.net/celestia/   

Celestia:  Celestia is a free real-time space simulation that lets you experience our universe in three dimensions. Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy. All travel in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.

  http://janus.astro.umd.edu/awtools.html#exploreorbits/ssbuild.html

Astronomy Workshop Tools:  A set of animations of various orbiting bodies, planets and moons.  There is a lot of information here, some of it suitable for high school and university physics classes, some great for demos for elementary classrooms.  Some highlights are on the pages below:

http://janus.astro.umd.edu/orbits/ssbuild.html
Design Your Solar System: World Builders, use this!!!  Put in some basic information and find out if your planets will support life!

http://janus.astro.umd.edu/javadir/orbits/ssv.html  
Solar System Viewer:
Animated solar system with inner planets, outer planets, asteroids, Kuyper Belt bodies and comets.  Enjoy!

http://janus.astro.umd.edu/javadir/orbits/ess.html
Extrasolar Planets: models of seven stars with real planetary systems detected by scientists.  

 http://ancientsuns.com/

Ancient Suns: This site gives us information on our closest neighboring star system, Alpha Centauri, which is actually a set of three stars bound together in a system by gravitational forces. It also shows us the orbits of three extra-solar planets that have been discovered by scientists, and shows the orbits of these planets in comparison with our own solar system. There is also a Viewing Cube animation of nearby stars which shows that we really do live in 3D space. Also included are some beautiful space scenes painted by this artist (respect copyright, please) and views of the night skies from other locations than our earth. There are also two software programs that you can download.

 http://liftoff.msfc.nasa.gov/academy/space/solarsystem/solarsystemjava.html

Explore the Solar System by The Exploratorium has an applet that shows the planets and other components of our solar system from a number of different perspectives. At the end of the presentation the viewer is able to tilt and rotate the solar system and see it from many different view points. Fun!

 http://probability.ca/jeff/java/manymoons.html

Many Moons shows groups of moons interacting according to the laws of gravity. Watch them go -- and notice that some wind up being ejected from the system and going off into space alone. This can happen with planets, too!

Binary Stars and Planets

 http://burtleburtle.net/bob/physics/index.html

Gravitational Interactions:  Links to Java applets show an interesting variety of possible orbits under many situations, such as more than one planet in the same orbit, planetary orbits in systems with binary stars, and planets moving in three dimensional space.  Java code and mathematical information are available, but you can enjoy the simulations and get the main ideas of the movements even if you do not have the mathematical background to understand the formulas and calculations.

 http://www32.brinkster.com/snefru/space/

Space by Simon Edgeworth: Featuring new stable orbits for planets, including the rounded-square orbit, the ice-cream-spoon orbit, and many more.  There are good diagrams, some java animations, and commentary to help us to understand what we are looking at.  The orbits simulated range from the simple to the complex, so choose one that you understand for your own planetary system!

 http://csep10.phys.utk.edu/astr162/lect/binaries/astrometric.html

Astrometric Binaries This page from an astronomy course has good information about binary stars.  Diagrams are excellent, and the material is presented with text, diagrams, and formulae, so that it is easy to understand.  The math is user friendly, and allows adventurous planet builders to figure out masses and distances if they wish.  There is information on how binary stars are discovered and studied, and links to further pages.
