First, the normal view of solar system. Cruithne is the purple ellipse. Earth is the blue circle. This simulation includes all the planet, but doesn't handle relativity, and the earth/moon system are lumped into one point. You can use the mouse to start and stop the image, and to move the view point (by dragging).	Sun Mercury Venus Cruithne Earth+Moon barycentre Mars Jupiter Saturn Uranus Neptune Pluto
Next, the most informative view the applet can manage, a strobe version drawn once per Earth year. Since every year Earth comes back to the same point in its orbit, and this is drawn once per year, Earth appears to stay fixed. Cruithne also has an orbit of almost one year, that's why consecutive purple dots are close to one another. Cruithne has an orbit slightly less than a year at first, then when it approaches Earth it slows down to slightly more than a year, and back and forth and back and forth. The little wobbles in Cruithne's orbit are apparently due to Jupiter. I didn't include any planets beyond Jupiter, for speed.	Sun Mercury Venus Cruithne Earth+Moon barycentre Mars Jupiter
Strobe version again. Side view. Earth remains a blue dot. Note that Cruithne is pretty far out of the main plane of the solar system. All the planets are included. You can drag the image if you want to try different viewpoints. The numbers in the upper left-hand corner are number of years, and energy difference from the start of the simulation. (Ideally energy is conserved, but the simulator isn't perfect.) Official estimates say Cruithne should leave this orbit in around 5000 years. This simulation says it stays in about the same orbit, but resonance gets spotty around 5000 years and goes away entirely around 10000.

Here's the same thing again, but with coordinates supplied by Paul Weigert, who is studying the orbit of Cruithne. Are this simulation and the previous one noticeably different (other than having slightly different viewpoints)? I'm not accounting for relativity. The simulation says the oscillation takes about 760 years. The official estimate is 770 years. Is that due to relativity or a bug in the simulator?

Finally, the normal view again, no strobe, no trails. Everything beyond Jupiter was removed for speed. Planets are drawn bigger than they really are.	Sun Mercury Venus Cruithne Earth+Moon barycentre Mars Jupiter
