On a.m. URL you find an image 'Astronav3.svg', replaced by '594px-Astronav3.svg.png'

In the image you find thin grey lines crossing the geocentre vertically and
horizontally as a kind of coordinate system. I drew these 2 lines as guide lines
for my construction, but marked the layer as "do not show / print" (in OOo
2.0.1), and in the original .svg view on
'http://upload.wikimedia.org/wikipedia/commons/5/5f/Astronav3.svg', for my
"Mozilla/5.0 (Windows; U; Windows NT 5.1; de-AT; rv:1.8.0.1) Gecko/20060130
SeaMonkey/1.0"  the lines are invisible, as it should be. 
But: IE6 (with adobe SVG viewer) also shows the lines. So I am not sure whether
this is a bug in Mediawiki-Software, OOo or Seamonkey.
