Eyeball Planets

[ysabetwordsmith]

Tidally locked planets tend to have very different conditions on the hot and cold sides.  This isn't a new idea, but the nickname is new and amusing.  It comes from the circular pattern of zones that can make a bullseye design.  This can have various configurations depending on how close the planet is to its sun.  The article includes several illustrations to show how they might look.

I would love to write this kind of setting.  It sounds like so much fun.
