------------------------------------------+---------------------------------
 In many cases, like in the image in the page "Planet" section "Orbit", a
 svg image is clipped, because there are not a easy way to scale a svg
 image to a fixed size using object. In the same page, in the section
 "Solar system" every planet have a svg with the symbol, and are clipped
 too.

 I have tried not set the width in the object, but we can't display the svg
 without setting a width because for example in the "Plant" page there are
 a lot of svg files and render at huge sizes.

 Now, in the pages in the online wikipedia, are using a thumbnail in png
 format. Rendered a small sizes, are lighther than the svg files in more
 cases.

 We can change our logic to use thumbnails to svg too.

 Example:

 A posible patch is attached, need more testing.
