Earth Day Special: The 10 Coolest Science Fiction Planets

It’s Earth Day, a holiday where we’ll all be thinking about what we can do for our little rocky ball three spots out from a medium sized yellow star.  Now, we don’t want to steal any of our dear old Earth’s thunder, but there are a number of other planets we think are deserving of recognition.

Certainly Mogo, the sentient planet Green Lantern, has done his share to keep peace in the galaxy.  Unicron, too, deserves recognition as a world devouring embodyment of chaos.  So we have complied a Power Grid list of the 10 Greatest Non-Earth Planets to grace the canon of Science Fiction.

As per usual, our Power Grids take into account the Google and Wikipedia popularity of each item, but this week’s list has the extra factor of Evolutionary Progress.  This refers to the relative sophistication of life on the planet, ranging from the completely barren orb, to the home of a space-faring civilization.
