Turning nonagon on 1.5degree counter-clockwise, we find that the five most important objects of system located around the sixth one - Rome multiply to 10 degrees with high accuracy.
Then having turned nonagon on 5.5 degrees clockwise, we see that the angle between St. Petersburg and Baalbeck is equal to 80 degrees, error 0.09 degree.
Rotation on 12 degrees clockwise gives us directions to Uluru, Solomon temple and Tiwanaku with minimal errors.
In this case, as we remember, direction to Tiwanaku is the orientation of the pentagram.
