A "sequel" to Lunar Spyrograph, this simulation uses real physics to simulate the orbit of earth around the sun.
But how would the orbit change under different circumstances?
Play around with this simulation to find out:
Will the earth stay on its orbit, or will it be catapulted into space!?

Nice simulator, but it's pretty basic.

Should be able to adjust Sun's Gravity. And a ability to scroll out a bit up to a distance of 2,000 away about.

Awsome, if it were somehow made more into a game, have some sort of like keep the orbit in this arc for 10 points or for the human race to survive, this is the foundation of a uniqely awsome game.

Lol awsome...

i love it put the starting velocity to X:5 Y:5 and watch the distance counter go up Awsome game lol

xytor responds:

You can get a higher speed just by setting the starting velocity to (0,0) from the reset position.
It crashes into the sun, and then it really takes off at a speed of about 24 (Pixels per Frame).

Playing with gravity has never felt... underdeveloped.
I don't want to talk about it.
