 ===Final comment===
-Wurm is a very strange and interresting planet. Even though it's in the middle of a pole switch and the current axis pitch is around 35° (which would be absolutely fatal for the life on planet earth), it is full of life and very habitable.

 '''Conclusions:'''<br>
   * Wurm's geographic north (rotation center) is towards Wurm's magnetic west.
-  * Sun rises in magnetic north (geo. east) and sets in magnetic south (geo. west).
+  * Sun rises in magnetic north (geo. east), travels around magnetic east (geo. south)  and sets in magnetic south (geo. west).
   * Sky rotates counter-clockwise around the visible rotation center.
   * We're located on the geographicaly north hemisphere of the Wurm planet (magneticaly west).

 First thing to find out was the angle per pixel scale, and for that we used simple trigonometry.
-Notch has once said that a tree in Wurm is approximately 12m high. Reading the distance to the nearest tree was no problem - it's just a matter of counting tiles and using simple trigonometry.<br>

 Then we had to find the exact rotation center and distance to the horizon in pixels (to calculate the angle). To find the horizon we simply used the same distance in pixels from a top of a distant mountain as on the photo above (photo aboce was taken looking directly west with eyes aligned on the horizon).<br>

+First, a look directly up in the sky, facing magnetic north. This picture was taken by clipping many pictures into one:<br>

 By looking at the picture we surprisingly concluded that the visible rotation center was somewhere near the western horizon, and not north or south as on earth.<br>
