Earth
This planet was by far the hardest for me to render properly. I've put together two different models of Earth; one is designed to be photo-realistic, and the other is designed after NASA's Blue Marble. Both models include optional night and city lights sections. These Earth models have been used in various productions by hobbyists and film groups. I've written a tutorial demonstrating how to build the models - you may find it here.
Some links to 2560x1920 renders of the models are below; these are my best renders. Some renders designed for use as desktop wallpapers may be found in the wallpaper section of this site.
