3D Model of the Solar System (Java)
Doesn't work? If you do not see a big square canvas to the left of this text: Your browser may not have Java enabled. I you see the square, but nothing on it: Your browser & hardware may be short on resources and need ~5 min. to start a new Java applet. Some old browsers may give a "Verify error" or a "File not found error". It should work fine for Netscape 3.01(32bit) and MS. I. Explorer 3.0

You could see the model Half the size of this! . Or you could go back to: Ulysses Home.

Note: This Planetarium calculates the orbits as ellipses following the old laws that Keppler, Huygens, Leibnitz, and others postulated in the 17th century, and that are still the cornerstones of Astrodynamics. The real orbits are pretty close to these ones.
