What we can learn from this simulation is: With specific initial position and initial velocity, a planet can have an unusual orbit like Mercury's under purely effect of Newton's Law of Universal Gravitation. This confirmed that Newton's theory can fully explain the precession of Mercury's perihelion.

For one revolution :

Darker color means: The Planet moving slower. Lighter color means: The Planet moving faster
