Comment 13 for bug 807841

I just tried to reduce the solar_system_observer distance:

orbit_SemiMajorAxis=5000000000

--> planets are visible. This is quite certainly an effect of the OpenGL far clipping plane distance. I think we can simply go closer like this, of course this changes perspective, the solar system observer is straight above the sun. If you want to have a top-down view zoomed in onto a planet, you would of course have to change its "parent object" to the selected object.
